Analysis 2: mortality rates (MR) per 100 person-years and hazard ratios (HR) of 6–35 months old DTP-vaccinated and diphtheria–tetanus–pertussis (DTP)-unvaccinated children.

	Mortality rate (deaths/person-years)		HR (95% CI)
	DTP(±OPV)	No DTP
All	5.4 (32/590.6) [553]	4.1 (10/242.5) [327]	1.48 (0.72–3.06)
Girls	6.9 (19/273.5) [270]	2.6 (3/116.4) [155]	2.91 (0.84–10.00)
Boys	4.1 (13/316.5) [282]	5.6 (7/125.1) [170]	0.88 (0.34–2.62)

Bandim, 1981–1983.

178 children were first DTP-unvaccinated and then received DTP during follow-up. Three children had no information on sex. If we adjusted for the most recent WAZ measurement, the HR of 1.48 (0.72–3.06) became 1.52 (0.74–3.15).
