Fig. 1. Overview of CAT-DI assessment frequency and source of variation in CAT-DI.

Fig. 1

a–c Box plot of the observed number of CAT-DI assessments (a), median number of days between assessments (b), and follow-up time in days (c) for each wave and treatment group. The numbers in the parentheses indicate the expected values for each of these metrics according to study design (Sup Fig. 2). The dark black line represents the median value; the box limits show the interquartile range (IQR) from the first (Q1) to third (Q3) quartiles; the whiskers extend to the furthest data point within Q1-1.5*IQR (bottom) and Q3 + 1.5*IQR (top). d Proportion of CAT-DI severity variance explained (VE) by inter-individual differences and other study parameters with 95% confidence intervals. The proportion of variance attributable to each source was computed using a linear mixed model with the individual id and season (two multilevel categorical variables) modeled as random variables and all other variables modeled as fixed (see Methods).
