  1. a) One mother of enrolled children had missing BCG scar information
  2. b) Four consented women had missing BCG scar information
  3. c) Distribution of background factors compared by binomial regression to express the association between scar and the background factors; intra-cluster correlation taken into account by robust standard error. Continuous variables grouped in quartiles
  4. d) Numbers do not add up since some had missing information on background factors
  5. e) Non-normal distributed variables presented by median and inter-quartile range (IQR)
  6. f) Three mothers of enrolled infants and 52 women in consent cohort had missing information on maternal age
  7. g) 57 mothers of enrolled infants and 243 women in consent cohort had missing information on number of antenatal consultations
  8. h) MUAC: Mid upper-arm circumference; SD: Standard deviation (SD). 14 mothers of enrolled infants and 157 women in consent cohort had missing information on MUAC
  9. i) Five mothers of enrolled infants and 12 women in consent cohort had missing information on parity
