---|---|---|---|---|
Mean (s.d.) | n | Mean (s.d.) | n | |
Baseline | 89 (15) | 247 | 86 (17) | 241 |
3 weeks post-surgery† | 51 (25) | 174 | 51 (27) | 173 |
6 weeks post-surgery | 61 (27) | 201 | 61 (26) | 209 |
3 months post-randomization | 68 (27) | 205 | 69 (25) | 208 |
Treatment effect (adjusted difference in means, n = 231 versus 232) |
2.3 (95% c.i. −1.7, 6.4) P = 0.256 |
*Scores are between 0 and 100, with higher scores indicating better function. A positive treatment effect indicates better mean function with hybrid surgery. †Assessment point at 3 weeks post-surgery introduced during the internal pilot.
