PRR: proportional reporting ratio; ROR: reporting odds ratio; IC: information component; EBGM: empirical Bayes geometric mean.
ROR-based signals were stratified into 5 groups; signals detected by the ROR only, signals detected by the ROR and PRR, signals detected by the ROR and IC, signals detected by the ROR, PRR, and IC, and signals detected by the 4 methods.
