Abstract

Some have questioned the evidence for performance-enhancing efects of several substances included on the World AntiDoping Agency’s Prohibited List due to the divergent or inconclusive fndings in randomized controlled trials (RCTs). However, inductive statistical inference based on RCTs-only may result in biased conclusions because of the scarcity of studies, inter-study heterogeneity, too few outcome events, or insufcient power. An abductive inference approach, where the body of evidence is evaluated beyond considerations of statistical signifcance, may serve as a tool to assess the plausibility of performance-enhancing efects of substances by also considering observations and facts not solely obtained from RCTs. Herein, we explored the applicability of an abductive inference approach as a tool to assess the performance-enhancing efects of substances included on the Prohibited List. We applied an abductive inference approach to make inferences on debated issues pertaining to the ergogenic efects of recombinant human erythropoietin (rHuEPO), beta2-agonists and anabolic androgenic steroids (AAS), and extended the approach to more controversial drug classes where RCTs are limited. We report that an abductive inference approach is a useful tool to assess the ergogenic efect of substances included on the Prohibited List—particularly for substances where inductive inference is inconclusive. Specifcally, a systematic abductive inference approach can aid researchers in assessing the efects of doping substances, either by leading to suggestions of causal relationships or identifying the need for additional research.
