Interaction estimates from the primary analysism, sensitivity analyeses, and prespecified subgroups. (A) Interaction measures on the ratio scale (ratio of rate ratios [RRR]). Each point represents an RRR estimate, with 95% CI represented by the capped bars. Values above one favor excess AKI with NSAID+RAS-I. (B) Interaction measures on the difference scale (difference in differences [DID]). Each point represents a DID estimate, with 95% CI represented by the capped bars. Values above zero favor excess AKI with NSAID+RAS-I. IPTW, inverse probability of treatment weighting; MV, multivariable.
