Notes. Two-level logistic regression with LGA random effect. Sample includes children up to 60 months of age (or aged 60 months at time of death) born between October 2000 and December 2017. Dependent variable: child is alive. Main results only, omitting child, parental and household determinants of immunisation, survey round dummy, constant and multilevel variance parameter. Using date approximations (year-month) as exact birth date information not available for children who did not survive. Total SIA exposure (EXP_TOT_nod) combines exposure during pregnancy and after birth and is used for interaction models (interaction terms were not statistically significant and were omitted from main results). Coefficients reported, 95% CIs in brackets.
