Preoperative vs. 6-month Postoperative K-MHQ Scores

Values are presented as mean ± SD.

K-MHQ: Korean version of the Michigan Hand Outcomes Questionnaire, SRM: standardized response mean.

^*All of the K-MHQ scales are based on a score from 0 to 100. For all of the scales except pain, a higher score translates into better performance for the patient's hand. For the pain scale, the relationship is inverse: the lower the score, the less pain the patient experiences, which signifies a better outcome.

^†Mean difference between preoperative and postoperative scores/standard deviation of mean difference. An SRM of 0.2 is considered small, 0.5 is considered medium, and 0.8 is considered large.
