| Note: %=Number of signals in each category divided by the total number of signals detected by each method multiplied by 100. The number after each method refers to various thresholds. Abbreviation: PRR=proportional reporting ratio; ROR=reporting odds ratio; BCPNN=Bayesian confidence propagation neural network; MGPS=multi-item gamma Poisson shrinker. * A represents the number of reports containing both the vaccine of interest and the AEFI of interest. | |||||||||
