Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Unclear risk | Quote: "Children were randomly assigned, with the use of block sizes of four, to receive one of four treatments." |
Allocation concealment (selection bias) | Unclear risk | Details not reported. |
Blinding of participants and personnel (performance bias) All outcomes | Low risk | Quote: "Children, study‐site investigators were unaware of the study‐group assignments. In the first day children were given either oxantel pamoate or identical placebo tablets. On the second day, children were administered two tablets albendazole or placebo table plus mebendazole." |
Blinding of outcome assessment (detection bias) All outcomes | Low risk | Quote: "Laboratory technicians were unaware of the treatment assignments." |
Incomplete outcome data (attrition bias) All outcomes | Low risk | 22 (4.6%) participants lost at follow‐up and not included in analysis. |
Selective reporting (reporting bias) | Low risk | All stated outcomes were reported. |
Other bias | Low risk | No obvious source of other bias. |
