AMB = AmBisome. MDAMB = multidose liposomal amphotericin B (AmBisome). MF = miltefosine. No. = number. PKDL = post-kala-azar dermal leishmaniasis. PMIM = paromomycin intramascular injection. SDAMB = single-dose liposomal amphotericin B (AmBisome). SSG = sodium stibogluconate. VL = visceral leishmaniasis.

^a Adjusted covariates: Age, Gender, Education, Monthly household expenditure, Number of family members in the household, Family member affected by VL in the past, Type of house, Presence of cattle shed, Number of bednets in the household, How often is the bednet used.
