* STH results at all visits include only children whose specimens were analyzed by the Kato-Katz method (i.e. 1Group 1 and Group 3 at 12-month visit; 2Groups 2 and 3 at 18-month visit (results were not available for 74 children who were lost to follow-up); 3All groups at the 24-month visit (results were not available for 197 children who were lost to follow-up))
ǂ1Group 1 (MBD/PBO) = mebendazole at the 12-month visit and placebo at the 18-month visit; 2Group 2 (PBO/MBD) = placebo at the 12-month visit and mebendazole at the 18-month visit; 3Group 3 (MBD/MBD) = mebendazole at the 12 and 18-month visit; 4Group 4 (PBO/PBO) = placebo at the 12 and 18-month visit
†AM = arithmetic mean eggs per gram;
§GM = geometric mean eggs per gram. A value of 1 was added to each observation to calculate the geometric mean.
