Association between SARS-COV-2 seropositivity over a 10-13 week period and demographic, hospital role and ethnicity in 1365 healthcare workers from London and Nottingham. All analyses are adjusted for age (per year), sex (male vs female), body mass index, index of multiple deprivation (IMD, per decile), hospital role (ITU vs non ITU, doctors vs other roles), presence of symptoms and ethnicity (vs Whites). Where the heterogeneity variance (τ2) is equal to 0 the fixed effect meta-analysis estimates are the same as random effects . Where τ2 >0 Dersimonian-Laird random effects estimates (indicated as Summary RE) are presented; .p-values shown for results that are statistically significant with p<0.05.
