| Δ Pinch strength (kg) | 6.2 | −2-33 | 15.0 | −9.8 | −28-9 | 25.8 | −15.95 | −41.2 to 9.3 |
Note. A 95% confidence with a lower limit below zero and an upper limit above zero represents a nonsignificant result. Δ = Change. If the patient with a tourniquet time of 208 minutes in the USO group is excluded, the difference in means for tourniquet time and corresponding bootstrapped 95% confidence interval are 37.8 minutes and 13.3 to 60.6, respectively. DRO = distal radius osteotomy; USO = ulnar shortening osteotomy; CI = confidence interval.
