Failure-mode index

Search what already failed

A searchable index of real negative results, null findings, and replication failures from the published literature — so you can learn what didn't work before repeating it.

WASTE indexes published research — it does not host or republish full papers. Each entry is a metadata record (title, authors, DOI) compiled from open scholarly databases, with the abstract shown in full only where the paper is openly licensed (e.g. Creative Commons); otherwise a short excerpt is shown for reference under fair use. WASTE classifies each work by failure type; classifications are automated and approximate.

The Helminth Parasite Heligmosomoides polygyrus Attenuates EAE in an IL-4Rα-Dependent Manner

Madeleine P. J. White, Chris Johnston, John R. Grainger et al. · 2020 · Frontiers in Immunology

Helminth parasites are effective in biasing Th2 immunity and inducing regulatory pathways that minimise excessive inflammation within their hosts, thus allowing chronic infection to occur whilst also suppressing bystander atopic or autoimmune diseases. Multiple sclerosis (MS) is a severe autoimmune disease characterised by inflammatory lesions within the central nervous system; there are very limited therapeutic options for the progressive forms of the disease and none are curative. Here, we used the experimental autoimmune encephalomyelitis (EAE) model to examine if the intestinal helminth He

To interact or not to interact: The pros and cons of including interactions in linear regression models

Aljoscha Rimpler, Henk A. L. Kiers, Don van Ravenzwaaij · 2025 · Behavior Research Methods

Interaction effects are very common in the psychological literature. However, interaction effects are typically very small and often fail to replicate. In this study, we conducted a simulation comparing the generalizability and estimability of two linear regression models: one correctly specified to account for interaction effects and one misspecified including simple effects only. We manipulated noise levels, predictor variable correlations, and different sets of regression weights, resulting in 9216 different conditions. From each dataset, we drew 1000 samples of N = 25, 50, 100, 250, 500, a

Mobile Money Use and Healthcare Utilization: Evidence from Rural Uganda

Hiroyuki Egami, Tomoya Matsumoto · 2020 · Sustainability

Lack of cash on hand is a significant obstacle in accessing healthcare services in developing countries. Many expectant mothers in the least developed countries do not receive sufficient care during pregnancy due to financial constraints. If such hurdles in accessing healthcare can be overcome, it will contribute to reduction in maternal and newborn mortality, which is a key target of Sustainable Development Goal 3. This study reports the first assessment of the impact of mobile money services on maternal care utilization. We hypothesize that mobile money adoption would motivate rural Ugandan

Investigating the DNA methylation profile of e-cigarette use

Rebecca C. Richmond, Carlos Sillero‐Rejon, Jasmine Khouja et al. · 2021 · Clinical Epigenetics

Abstract Background Little evidence exists on the health effects of e-cigarette use. DNA methylation may serve as a biomarker for exposure and could be predictive of future health risk. We aimed to investigate the DNA methylation profile of e-cigarette use. Results Among 117 smokers, 117 non-smokers and 116 non-smoking vapers, we evaluated associations between e-cigarette use and epigenome-wide methylation from saliva. DNA methylation at 7 cytosine-phosphate-guanine sites (CpGs) was associated with e-cigarette use at p < 1 × 10 –5 and none at p < 5.91 × 10 –8 . 13 CpGs were associated wi

Testing Efficiency of the London Metal Exchange: New Evidence

Jaehwan Park, Byungkwon Lim · 2018 · International Journal of Financial Studies

This paper explores the market efficiency of the six base metals traded on the LME (London Metal Exchange) using daily data from January 2000 to June 2016. The hypothesis that futures prices 3M (3-month) are unbiased predictors of spot prices (cash) in the LME is rejected based on the false premise that the financialization of commodities has been growing. For the robustness check, monthly data is analyzed using ordinary least squares (OLS) and GARCH (1,1) models. We reject the null hypothesis for all metals except for zinc.

A validation study of the psychometric properties of the Groningen Reflection Ability Scale

Nina Bjerre Andersen, Lotte Dyhrberg O’Neill, Lise Kirstine Gormsen et al. · 2014 · BMC Medical Education

BACKGROUND: Reflection, the ability to examine critically one's own learning and functioning, is considered important for 'the good doctor'. The Groningen Reflection Ability Scale (GRAS) is an instrument measuring student reflection, which has not yet been validated beyond the original Dutch study. The aim of this study was to adapt GRAS for use in a Danish setting and to investigate the psychometric properties of GRAS-DK. METHODS: We performed a cross-cultural adaptation of GRAS from Dutch to Danish. Next, we collected primary data online, performed a retest, analysed data descriptively, esti

Perinatal and psychosocial circumstances associated with risk of attempted suicide, non-suicidal self-injury and psychiatric service use. A longitudinal study of young people

Robert Young, Daniel Vincent Riordan, Cameron Stark · 2011 · BMC Public Health

BACKGROUND: Past studies using large population based datasets link certain perinatal circumstances (birth weight, parity, etc) with mental health outcomes such as suicide, self-harm and psychiatric problems. Problematically, population datasets omit a number of social confounds. The aim of this study is to replicate past research linking perinatal circumstances and mental health (suicidality and use of psychiatric services) and to determine if such associations remain after adjusting for social circumstances. METHODS: A longitudinal school-based survey of 2157 young people (surveyed at age 11

Immunomodulatory Mechanisms of Chronic Wound Healing: Translational and Clinical Relevance

Mahrukh Riaz, Muhammad Zohaib Iqbal, Agnes S. Klar et al. · 2025 · MedComm

Chronic wounds-such as diabetic foot ulcers (DFUs), pressure ulcers (PUs), and venous leg ulcers (VLUs)-pose a serious clinical challenge due to their prolonged inflammatory phase and impaired healing. Increasing evidence reveals that dysregulated immune responses are central to the pathogenesis of chronic wounds. A complex interplay between innate and adaptive immune cells, including macrophages, neutrophils, and T cells, contributes to chronic inflammation, extracellular matrix (ECM) degradation, and tissue repair failure. While current treatments target symptoms, they often overlook the und

Acute minocycline administration reduces brain injury and improves long-term functional outcomes after delayed hypoxemia following traumatic brain injury

Marta Celorrio, Kirill Shumilov, Camryn Payne et al. · 2022 · Acta Neuropathologica Communications

Clinical trials of therapeutics for traumatic brain injury (TBI) demonstrating preclinical efficacy for TBI have failed to replicate these results in humans, in part due to the absence of clinically feasible therapeutic windows for administration. Minocycline, an inhibitor of microglial activation, has been shown to be neuroprotective when administered early after experimental TBI but detrimental when administered chronically to human TBI survivors. Rather than focusing on the rescue of primary injury with early administration of therapeutics which may not be clinically feasible, we hypothesiz

Elevating the field for applying neuroimaging to individual patients in psychiatry

David R. Roalf, Martijn Figee, Desmond J. Oathes · 2024 · Translational Psychiatry

Although neuroimaging has been widely applied in psychiatry, much of the exuberance in decades past has been tempered by failed replications and a lack of definitive evidence to support the utility of imaging to inform clinical decisions. There are multiple promising ways forward to demonstrate the relevance of neuroimaging for psychiatry at the individual patient level. Ultra-high field magnetic resonance imaging is developing as a sensitive measure of neurometabolic processes of particular relevance that holds promise as a new way to characterize patient abnormalities as well as variability
