Mdn, Median; IQR, interquartile range; U, Mann–Whitney U test.

Severe, scores 1 or 2 on long term threat; Escape, score of 2 or 3 on escape rating.

Three-way comparison between groups (CD v. HC v. DEP) significant for all comparisons (p ⩽ 0.05) using Kruskal–Wallis.

^aNumber of events in each epoch are converted to a rate over 1 year (‘annualized’) allowing direct comparisons between epochs of different lengths (note that epochs are not exclusive).

*p ⩽ 0.05, **p ⩽ 0.01, ***p ⩽ 0.001.
