Schematic presentation of sampling procedure to assess the predictors among HIV-infected children on ART in Amhara Region Referral Hospitals from January 1, 2012 to February 28, 2017. Footnote: proportion was calculated as follows: the total number of HIV-infected children on ART at a given hospital between January 1, 2012 and February 28, 2017 multiplied by our calculated sample size (553), then divided by the total number of HIV-infected children started ART in the three hospitals between January 1, 2012 and February 28, 2017 (740). For example, for DMRH, it was calculated as: 205*553/740 = 153
