Sensitivity analysis - effect of bias due to loss to follow-up – worst case scenario

Duration of cART	Number of children left	Deaths	Follow-up years	Mortality Rate, deaths per 100 person-years (95% CI)
3 months	956	36	248	14.5 (9.7–19.2)
6 months	901	68	478	14.2 (10.8–17.6)
1 year	822	106	908	11.6 (9.4–13.9)
2 years	710	145	1672	8.7 (7.2–10.8)
5 years	387	200	3326	6.0 (5.1–6.9)
10 years	25	229	4225	5.4 (4.7–6.1))

We assumed that all the patients who were lost to follow-up survived for 90 days after their last clinical visit then died
