Flowchart detailing the number of participants included in the three sub-studies. Insufficient parasitological data corresponds to one (out of four) or more missing diagnostic examinations for S. stercoralis, to one (out of two) or more missing diagnostic examinations for other helminths, and to any missing diagnostic examination for protozoa.

Proportion of participants harboring S. stercoralis mono-infections and reporting abdominal pain, nausea, vomiting, diarrhea, urticaria, and cough before and 21 days after ivermectin (200 μg/kg BW) treatment.
The decreases in the proportion of participants reporting any of the symptoms in the figure was significant at 5% level, as assessed by the McNemar’s test. S. stercoralis low parasite load: positive count and ≤ 1 larvae per gram (LPG). S. stercoralis moderate or high parasite load: > 1 LPG. Data were collected in 2012 in Preah Vihear Province, North Cambodia, from 103 participants in the post-treatment survey who harbored S. stercoralis mono-infection at both surveys and met the case definitions used in this work for all parasites.
