Table 5 Sensitivity analysis - effect of bias due to loss to follow-up – worst case scenario

From: Long-term survival outcomes of HIV infected children receiving antiretroviral therapy: an observational study from Zambia (2003–2015)

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