Effect of maternal and paternal BCG scars on mortality between 42 days and 1 year of age.
| Mortality rate [Deaths/100 Person years] (n) |

Adjusted MRR (CI) (Scar/No scar)c |

|---|---|---|---|---|
| BCG scar | No BCG scar | |||
| Maternal | 4.8 [14/2.9] (340) | 4.7 [4/0.86] (99) | 1.03 (0.34–3.10) | 1.60 (0.51–5.05)d |
| Paternala | 4.4 [5/1.1] (132) | 3.1 [2/0.65] (75) | 1.41 (0.27–7.35) | 1.80 (0.34–9.43)e |
| Both parentsb | 4.0 [3/0.75] (87) | 3.1 [2/0.64] (73) | 1.27 (0.21–7.57) | 1.53 (0.26–9.20)f |
a
One infant migrated within 42 days (no paternal scar).
b
BCG scar’ equals both parents with a scar and ‘No BCG scar’ equals either one or none of the parents with a scar.
c
The Cox proportional hazards model was adjusted by stabilized Inverse Probability of Treatment Weighting based on the variables maternal schooling, electricity, indoor toilet and age of the child at inclusion.
d
Proportional hazards = 0.48.
e
Proportional hazards = 0.14.
f
Proportional hazards = 0.59. Abbreviations: BCG, Bacillus Calmette-Guérin; CI, confidence interval; MRR, mortality rate ratio.
