Title: | The Net Benefit of a treatment should take the correlation between benefits and harms into account | Authors: | BUYSE, Marc Saad, Everardo D. Peron, Julien Chiem, Jean-Christophe De Backer, Mickael Cantagallo, Eva Ciani, Oriana |
Issue Date: | 2021 | Publisher: | ELSEVIER SCIENCE INC | Source: | JOURNAL OF CLINICAL EPIDEMIOLOGY, 137 , p. 148 -158 | Abstract: | Objective: The assessment of benefits and harms from experimental treatments often ignores the association between outcomes. In a randomized trial, generalized pairwise comparisons (GPC) can be used to assess a Net Benefit that takes this association into account. Study design and settings: We use GPC to analyze a fictitious trial of treatment versus control, with a binary efficacy outcome (response) and a binary toxicity outcome, as well as data from two actual randomized trials in oncology. In all cases, we compute the Net Benefit for scenarios with different orders of priority between response and toxicity, and a range of odds ratios (ORs) for the association between these outcomes. Results: The GPC Net Benefit was quite different from the benefit/harm computed using marginal treatment effects on response and toxicity. In the fictitious trial using response as first priority, treatment had an unfavorable Net Benefit if OR < 1, but favorable if OR > 1. With OR = 1, the Net Benefit was 0. Results changed drastically using toxicity as first priority. Conclusion: Even in a simple situation, marginal treatment effects can be misleading. In contrast, GPC assesses the Net Benefit as a function of the treatment effects on each outcome, the association between outcomes, and individual patient priorities. (C) 2021 The Authors.
