Methods	Quasi‐RCT Length of follow‐up: 1.75 months (7 weeks)
Participants	All children living in endemic area Number analysed for primary outcome: 64 Age range: 6 to 10 years Inclusion criteria: boys aged 6 to 10 years attending second grade at 3 primary schools; completed assessment and provided a stool sample; randomized by descending hookworm count (all treated) Exclusion criteria: none stated
Interventions	Single dose vs placebo Pyrantel pamoate: 10 mg/kg; Placebo.
Outcomes	Mean weight post‐treatment; Appetite: consumption test (mL porridge) and self assessment. Not included in review: egg counts arithmetic and geometric means (Kato‐Katz); weight‐for‐age (NCHS reference)

Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Randomized: "Randomly assigned" by descending A. lubricoides egg count"
Allocation concealment (selection bias)	Unclear risk	No details reported.
Blinding (performance bias and detection bias) All outcomes	Unclear risk	"Double‐blind". Participants blinded both placebo and treatment identical round white tablets, no information about provider and assessor blinding.
Incomplete outcome data (attrition bias) All outcomes	Low risk	85% (64/75) of randomized participants were evaluated. Reasons for loss to follow‐up included: moved away, refused to be examined, did not return a stool sample, absent during examination. Not clear how many lost from each treatment group. Inclusion of all randomized participants (number evaluable/number randomized): 85% (64/75).
Selective reporting (reporting bias)	Low risk	All stated outcomes reported.
Other bias	Low risk	No obvious other source of bias.
