Surgery plus physiotherapy vs placebo surgery plus physiotherapy (Pain).
| Population: patients with subacromial impingement syndrome. Settings: inpatient clinics. Intervention: Surgery plus Physiotherapy Comparison: Placebo Surgery plus Physiotherapy Follow up: 3-, 6-months and 1- and 2-years | |||

1We downgraded by one level due to high risk of bias.
2We downgraded by one level due to a relatively small sample size.
