Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk Quote: "Block randomization was performed with even distribution, using computer‐generated numbers."
Comment: appropriate method of random sequence generation.
Allocation concealment (selection bias) Unclear risk Comment: allocation concealment not addressed.
Blinding of participants and personnel (performance bias)
All outcomes Low risk Quote: "placebo‐controlled, randomized, double‐blind study": "the patients were randomized into either placebo or study group."
Comment: participants likely blinded.
Blinding of outcome assessment (detection bias)
Investigator assessed; not susceptible (auxiliary treatments) Low risk Comment: outcome judged not susceptible to detection bias.
Blinding of outcome assessment (detection bias)
Investigator assessed; susceptible (stone clearance, time to stone clearance) Unclear risk Comment: blinding of outcome assessors not addressed.
Blinding of outcome assessment (detection bias)
Investigator assessed; susceptible (major adverse events) Unclear risk Comment: blinding of outcome assessors not addressed.
Incomplete outcome data (attrition bias)
All outcomes Low risk Quote: "of the 60 patients randomized 58 completed the study, and one from each group discontinued medication and was excluded from analysis."
Comment: low (< 10%) loss to follow‐up.
Selective reporting (reporting bias) Unclear risk Comment: no protocol available.
Other bias (additional SWL sessions) Unclear risk Comment: unclear whether > 1 SWL session was administered.
