| High-frequency feedback group (HFF group) N = 23 | Low-frequency feedback group (LFF group) N = 24 | p-value 2 | |
| Peyton’s step 4 (T1) | 5.31 ± 0.50 | 5.30 ± .64 | .941 |

Performance ratings of the two groups in Peyton’s step 4 (T1) and in the final, 6th repetition (T2) in task-specific clinical skill performance (binary checklist rating as mean score in percent of maximum achievable points and standard deviation; checklist of 16 items with a minimum of 0 and a maximum of 16 points; ANOVA, p-values) and global procedural performance (global performance rating as mean score of global rating scales ± standard deviation; six-point Likert scale from 6 = very good to 1 = unsatisfactory; M-W-U-Test, p-values).
