Mixed model of ECP using nested random effects for a 19-d (7 d TDS + 12 d BD) DMSA chelation course (n = 2,285 in unadjusted analysis; n = 2,262 in adjusted analysis limited to patients with data on all covariates).

A positive value of ECP indicates an increase in VBLL; a negative value of ECP indicates a decrease in VBLL. DOT by clinic staff; non-DOT doses administered by caretaker.*Total patients in unadjusted analyses = 2,285. Final model (n = 2,262) excludes those with missing data (1%).†Adjusted for all other variables shown in the table.‡An end-course VBLL was accepted if up to 2 d before and up to 10 d after last dose of DMSA.Mixed model of ECP using nested random effects for a 19-d (7 d TDS + 12 d BD) DMSA chelation course (n = 2,285 in unadjusted analysis; n = 2,262 in adjusted analysis limited to patients with data on all covariates).
