Table 1. Treatments administered by each study and respective study characteristics for included efficacy studies.

Reference no.	Study	IVM + ALB	ALB alone (or with placebo)	IVM alone (or with placebo)	Country	Studied parasites	Follow-up period	Age group	No. stool samples
[18]	Belizario et al., 2003	X	X	X	Philippines	T. trichiura A. lumbricoides	7–14 days	6–12	1 at baseline 1 at follow-up
[19]	Ismail et al., 1999	X	X		Sri Lanka	T. trichiura	3 weeks	4–14	1 at baseline 1 at follow-up
[20]	Knopp et al., 2010	X	X		Tanzania	T. trichiura A. lumbricoides Hookworm	22–39 days	6–20	2 at baseline 2 at follow-up
[24]	Speich et al., 2015*	X			Tanzania	T. trichiura A. lumbricoides Hookworm	18–23 days	6–14	2 at baseline 2 at follow-up

Note: IVM + ALB = co-administration of ivermectin-albendazole, ALB = albendazole, IVM = ivermectin.

*Speich et al. 2015 [24] compared ivermectin-albendazole to albendazole-mebendazole, albendazole-oxantel pamoate and mebendazole alone.
