Volcano plot showing the association between J-ARS drugs and anticholinergic syndrome-related adverse events in the JADER database. The horizontal axis represents the natural logarithm of the reported odds ratio (lnROR), and the vertical axis shows the reciprocal of -log(P-value) obtained from Fisher’s exact test. The horizontal line indicates the criterion of -log(P-value) = 1.3 (P = 0.05). Color-coded categories represent different types of adverse events related to anticholinergic syndrome
