BACKGROUND: Randomized clinical trials (RCT) in critical care mostly return negative results. The research community discusses strategies to improve RCTs design. METHODS: This paper presents a theoretical framework based on marginal utility to treat the problems of hypothesis generation and treatment effects valuation and presents recently published high-quality studies as instances where such a framework predicts irrelevant findings. RESULTS: Blindness to marginal utility, i.e., inobservance of the marginal utility of the proposed intervention, is common in critical care RCTs. CONCLUSION: Critical care RCTs are usually blind to marginal utility and are, therefore, prone to produce irrelevant findings.
