Objective evaluation of Traceculectomy Sim-OSSCAR scores: intervention versus control groups
| Timing of simulation trabeculectomy competency assessment | Intervention Score*, mean (%) (SD) | Control Score*, mean (%) (SD) | Difference† Score* | 95% CI Score* | P value |
| Baseline | 9.1 (22.6) (5.0) | 8.7 (21.8) (3.7) | −0.3 | −2.8 to 2.2 | 0.788 |
| Final day of training course‡ | 30.7 (76.9) (5.1) | 21.7 | 19.0 to 24.4 | (0.117)‡ | |
| 3-month (primary outcome) | 30.4 (76.1) (4.4) | 9.8 (24.4) (3.6) | 20.6 | 18.3 to 22.9 | <0.001 |

*Score out of 40 points.
†Adjusting for training centre as a fixed effect.
‡Training course intervention was after 12 months for control participants (p=0.177 relates to intervention vs control on final day of training course).
