Calcium paradox in skeletal muscles: physiologic and microscopic observations.

abstract：INTRODUCTION:Previous studies have reported higher wrist ratios (WR) related to carpal tunnel syndrome (CTS) but have not assessed effect modification by obesity and may have inadequately controlled for confounders. METHODS:Baseline data of a multicenter prospective cohort study were analyzed. CTS was defined by nerve...
