Combined forest plot of the adjusted effect of vitamin A supplementation on infant mortality, stratified by DTP vaccination statusFig. 1Description: These estimates correspond with estimates presented in Table 3 of the main paper. Hazard Ratios were combined by through a fixed-effect metanalysis of the adjusted estimates from Tanzania and Ghana. All hazard ratios are calculated using Cox proportional hazards models allowing for time-varying vaccination status and are controlled for continuous birthweight (with spline knots at 1.5, 2, 2.5, and 3.5 kg), head of household (mother, father, grandmother, grandfather, other), household religion (Christian, Muslim, None, Traditional African), maternal age (<20, 20–24, 25–29, 30–34, 35–39, ≥40), maternal education (None, Primary, Secondary for Tanzania, and additionally Post-secondary for Ghana), multiple or singleton birth, number of living children in household (0, 1, 2, 3 + ), number of children in household who have died (0, 1, 2, 3 + ), place of birth (Home, Facility, Other), site ID (1–4 for Ghana and 1–2 for Tanzania), wealth quintile, delivery type (vaginal or caesarean), and maternal megadose of vitamin A.
