| Parameters | Surgeons | Laymen | p-value |
|---|---|---|---|
| Screw head detection time [min] | 00:54 (00:31 to 02:45) | 00:50 (00:29 to 02:10) | 0.51 |
| Median total bending time [min] | 04:52 (02:37 to 22:08) | 07:00 (03:50 to 17:00) | 0.74 |
| First bending [min] | 03:08 (02:07 to 05:55) | 06:24 (03:50 to 10:39) | 0.004 |
| Re-bending 1 [min] | 02:43 (02:20 to 07:49) | 00:53 (00:25 to 05:30) | 0.17 |
| Re-bending 2 [min] | 08:43 (08:43 to 08:43) | 02:20 (00:40 to 04:00) | 0.27 |
| Number of re-bends | 6 | 6 | 1 |
