St. Mark’s score preoperatively, at 6 weeks postoperatively and at long-term follow-up
| All participants (N = 94) | Mean | 95% CI | Median | Interquartile range | Minimum–maximum |
|---|---|---|---|---|---|
| St. Mark’s score preoperatively | 12.6 | 11.6 to 13.5 | 13.0 | 7.0 | 3 to 23 |
| St. Mark’s score at 6 weeks postoperatively | 3.7 | 2.9 to 4.6 | 2.5 | 6.0 | 0 to 19 |
| St. Mark’s score at long-term follow-up | 7.9 | 6.7 to 9.1 | 6.5 | 7.0 | 0 to 23 |
| Reduction in preoperative St.Mark’s score at long-term follow-up, all participants (N = 94)a | 4.7 | 3.5 to 5.9 | 4.5 | 7.0 | − 12 to 19 |
| Reduction in preoperative St.Mark’s score at long-term follow-up, internal anal sphincter adapted (N = 47)a | 6.3 | 4.4 to 7.9 | 6.0 | 8.0 | − 12 to 19 |
| Reduction in preoperative St.Mark’s score at long-term follow-up, internal anal sphincter dehiscent (N = 29)a | 0.5 | − 2.1 to 2.9 | 2.0 | 5.0 | − 11 to 12 |
a In the rows showing the values for the reduction in preoperative St. Mark’s score long-term follow-up values, positive numbers indicates an improvement of anal continence and negative numbers indicate worsening
