Kaplan-Meier curve of survival probability by parental BCG scar status. Adjusted mortality rate ratios (aMRRs) for maternal BCG scar (A) and paternal BCG scar (B) estimated in a Cox proportional hazards model with time since randomization as the underlying time variable. Models were adjusted by stabilized Inverse Probability of Treatment Weighting (sIPTW) based on the variables maternal schooling, electricity, indoor toilet and age of the child at inclusion. Observations were censored at migration or 42 days of age, whatever came first. Numbers at risk and numbers censored (bracketed) are rounded to the nearest integer because of the sIPTW. Abbreviations: BCG, Bacillus Calmette-Guérin.
