Risk-based heterogeneity of treatment effect of SUP on 28-day mortality. Risk group 1 means the lowest risk of death, and group 10 means the highest risk of death. Clinical benefit was deemed substantially more probable than not (posterior probability of an OR > 1, 1.9%) in the highest risk group. SUP, stress ulcer prophylaxis; OR, odds ratio; Crl credible interval. aPosterior probability of an OR greater than 1
