Summary of results of between-group SMD for primary outcomes of included randomised controlled trials
| Study | Title, journal | Baseline M (SD) PT | Baseline M (SD) control | Primary FU M (SD) PT | Primary FU M (SD) control | Other FU M (SD) PT | Other FU M (SD) control | Did primary FU score reach ? | Proportion of participants with FU score greater than PASS score | PT group change score (primary outcome primary end point) | Control group change score primary outcome primary end point) | Did primary change score reach MIC? | Between-group SMD (95% CI) for primary outcomes (positive SMD favours PT intervention) |
