  1. *CI indicates confidence interval and HR indicates hazards ratio(s) obtained from Cox proportional hazards models.
  2. aThe HRs are adjusted for the variables for which a HR is given as well as for age of the child in days at the time of receiving the BCG vaccine. Clustering by the randomization units in the PROMISE-EBF trial was also taken into account.
