DK = Don't know, IgG = Immunoglobulin G.
Bold indicates statistical significant value.
a
Assigned measles IgG positive if >250 IU/L.
b
Assigned rubella IgG positive if >10 IU/mL.
c
Fisher's exact test was used to assess associations between VPD seropositivity and other categorical variables.
d
Hepatitis B serostatus was treated as a binary variable (level 1 = active hepatitis B infection, level 2 = all other categories).
e
Reference for variables with multiple categories.
