Fig. 4.

Separate mixed-effects logistic regression models calculating the odds for each outcome in HCPs compared with non-HCPs at baseline, phase 2 and phase 3. Blue plots denote risk (odds) with 95% confidence intervals for HCPs to meet criteria for outcomes, relative to non-HCPs (red line). The number of participants included in each regression model varied slightly for each outcome and for each phase (see Supplementary Table 6 for participant numbers with valid data for each outcome at each phase). HCP, healthcare professional; SWEMWBS, Short Warwick–Edinburgh Mental Wellbeing Scale.
