learning gain
81.5% of students were female and 18.5% were male (p<0.001).A statistically significant learning gain in the knot tying and suturing technique with the DH was shown only in the DH group when compared to the NDH and AT groups. The learning gain in knot tying and suturing technique with the DH between groups NDH and AT did not differ significantly (see table 1 Subgroup analysis showed a significantly more frequently reported prior experience with surgical knot tying and suturing techniques among those students who studied in the more progressed clinical section of their studies when compared to students who were still involved in their preclinical studies. Students in the clinical section achieved a statistically significantly higher learning gain in knotting technique with the DH when compared to students in the preclinical study section regardless of the type of training applied (difference OSATS knots) (see table 2 Subgroup analysis revealed that most students with learning gains in their knot tying technique with the DH (≥4 OSATS points) had training with the DH (46.4%) (see table 3
