| Participants | Bilateral valgus deformity knee OA: N = 30 All female Mean age (years): 62 Mean BMI (kg/m2): 30 Degree of OA lateral compartment according to Kellgren & Lawrence: II = 16, III = 8, IV = 6 |
|
| Interventions | I = medially wedged insole (n = 16) vs C = neutral insole (n = 14) Follow‐up: 2 months |

| Outcomes | VAS pain (night, rest, movement), Lequesne index score, WOMAC | |
| Notes | ||
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk | Randomisation sequence procedure is not described |
| Allocation concealment (selection bias) | Unclear risk | Allocation concealment procedure is not described |
| Blinding (performance bias and detection bias) All outcomes | Low risk | Double‐blind trial |
| Blinding of participants and personnel (performance bias) All outcomes | Low risk | Quote: "patients of both groups received the same new shoe and were blind to insole use" |
| Blinding of outcome assessment (detection bias) All outcomes | Low risk | Quote: "outcomes were administered at baseline and after 8 weeks by a blinded examiner" |
| Incomplete outcome data (attrition bias) All outcomes | Low risk | Complete data were reported |
| Selective reporting (reporting bias) | Low risk | Complete data were reported |
