Seropositivity counts (proportions) are split by VD category (columns) and by a set of variables (rows). Seropositivity proportions within a row are defined as the count of SARS-CoV-2 seropositive (or seronegative) subjects within that VD category, divided by the total count within that group.
BAME, black, Asian and minority ethnic; BMI, body mass index; VD, vitamin D.
