Population monitored through NIE-ELISA with paired samples

	G1 (MDA + W and S intervention) (N = 116)	G2 (MDA intervention) (N = 86)	P value
Age (year)	10 (6.3–13)*	14 (83–2.3)*	0.0056
Female sex (%)	56.9 (66/116)	67.4 (58/86)	0.1452
Interval between B/L and F/U (days)	331 (330–395)*	508 (282–549)	< 0.0001
Incident cases (%)† between B/L and F/U	1.2 (1/83)	8.7 (4/46)	0.0347

B/L = base line; ELISA = enzyme linked immunosorbent assay; F/U = follow-up; G1 = Group 1; G2 = Group 2; IQR = interquartile range; MDA = massive drug administration; W and S = water and sanitation facilities.
