Comment on “Evaluating the Association Between Obesity and Development of Trigger Finger and Carpal Tunnel Syndrome”

The publication on “Evaluating the Association Between Obesity and Development of Trigger Finger and Carpal Tunnel Syndrome”1 is interesting. In this study, the researchers used a retrospective chart review method, which has notable limitations. The data may be inadequate or lacking specific aspects, such as the real onset of symptoms before diagnosis, which may affect the accuracy of age measurement at the time of diagnosis. The classification of body mass index (BMI) groups based on only two standard criteria (BMI ≥ 30 and BMI 18.5–24.9) may overlook the effects of different levels of body weight and obstruct the potential differences in the overweight but not obese group, such as the BMI 25–29.9 group, which may also be a risk group.
