| Risk of bias |
| Bias |
Authors' judgement |
Support for judgement |
| Random sequence generation (selection bias) |
High risk |
Randomisation sequence based on last 2 digits of telephone number |
| Allocation concealment (selection bias) |
High risk |
Inadequate, following communication with the author (Edelson 2002 (pers comm)) |
| Incomplete outcome data (attrition bias)
All outcomes |
Low risk |
1 lost to follow‐up due to transport problems |
| Selective reporting (reporting bias) |
Low risk |
The outcomes listed in the methods are reported in the results |
| Other bias |
Unclear risk |
"Funding was provided in part by the Adriana Foundation and the Alex Kunin Fund." |
| Blinding of participants and personnel (performance bias)
All outcomes |
Low risk |
Parents were blinded. Investigators not blinded as they were required to set and administer treatment. Investigators did not conduct pre‐ or post‐assessments |
| Blinding of outcome assessment (detection bias)
All outcomes |
Low risk |
Outcomes assessors blinded |
