Data are presented as median number of patients if not stated otherwise.

Abbreviations: ∆, median of differences between the number of patients before pandemic and during April 2020; ∆%, median of relative differences in number of patients calculated as the number of patients (April—before)/before; CI, Bonett-Price confidence interval for median; IQR, interquartile range; n, number of participants; M, median; p, statistical significance of the absolute difference calculated using Wilcoxon rank-sum (Mann–Whitney U) test.

^aThere were 4 (0.7%) missing data for number of patients during April 2020; 5 (0.8%) for number tested; and 6 (1.0%) for number infected.

^bFDR < 5%.

^cSamples were weighted for the total number of psychiatrists in particular countries.
