Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Comment: method of random sequence generation not described.
Allocation concealment (selection bias) Unclear risk Comment: allocation concealment not addressed.
Blinding of participants and personnel (performance bias)
All outcomes High risk Comment: no mention of placebo; participants likely not blinded.
Blinding of outcome assessment (detection bias)
Investigator assessed; susceptible (stone clearance, time to stone clearance) High risk Comment: unlikely that outcome assessors were blinded.
Blinding of outcome assessment (detection bias)
Investigator assessed; susceptible (major adverse events) High risk Comment: unlikely that outcome assessors were blinded.
Incomplete outcome data (attrition bias)
All outcomes Unclear risk Comment: unable to assess what proportion of randomized participants were included in outcome analyses.
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.
