| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Not adequately described |
| Allocation concealment (selection bias) | Unclear risk | Not adequately described |
| Blinding of Participants (performance bias) | High risk | Not possible owing to differences between interventions |
| Blinding of Personal (performance bias) | High risk | Not possible owing to differences between interventions |
| Blinding of the Outcome assessor (detection bias) | High risk | Not possible owing to differences between interventions |
| Incomplete outcome data (attrition bias) | Low risk | No dropouts |
| Randomized Participants analysed were allocated (attrition bias) | Low risk | No dropouts |
| Selective outcome (reporting bias) | Unclear risk | No protocol |
| Similar groups at baseline? | Unclear risk | Data were given only for age and pain; missing for other characteristics |
| co‐interventions avoided or similar? | Unclear risk | Not described |
| Compliance acceptable? | Low risk | Table 1 – appears that all received 12 treatments. |
| Similar timing of outcome assessment? | Low risk | Baseline, 2 weeks |
