Characteristics of the 214 children recruited that either received albendazole treatments (107 children) or no treatment (107 children). GM - geometric mean. SD - standard deviation. Epg - eggs per gramme of stool. t - time of observations (t=0, baseline or pre-treatment; t=12, at 12 months of follow-up)
a
Includes positive allergen skin tests to A. tenuis, cat, grass pollen mix, and fungimix.
b
Infection intensities calculated excluding non-infected children.
c
Number of directly observed treatments with single doses of 400 mg of albendazole
