Prevalence of helminth infections at posttreatment time points

Study group	N	Any spp., n (%)	Hookworm, n (%)†	A. lumbricoides, n (%)†	Trichuris trichiuria, n (%)‡
9 mo
Placebo	227	191 (84.1)	160 (70.5)	76 (33.5)	72 (31.7)
Albendazole	181	94 (51.9)**	59 (32.6)**	24 (13.3)**	38 (21.0)**
21 mo
Placebo	215	171 (80.0)	144 (67.0)	52 (24.2)	62 (28.8)
Albendazole	148	58 (39.2)**	32 (21.6)**	18 (12.2)**	24 (16.2)**

**P values were generated from the modeled data for combined effect of albendazole treatment over time and were significant (P < 0.001) for any helminth and for each of the species separately. N, total number per group; n, number of infected subjects.

^†Diagnosed by PCR.

^‡Diagnosed by microscopy.
