The height, weight and calf sizes of 19 carriers of X-linked Duchenne muscular dystrophy were compared with 32 normal female controls of comparable age. Whereas the regression of the sum of right and left calf sizes on weight was highly significant in both groups, the difference between right and left calf size showed no significant association with weight, height or age. There was no significant difference between carriers and controls in the sum of calf sizes either before or after correction for weight by Analysis of Covariance and no significant difference between the two groups in the degree of asymmetry of right and left calf size.
将19名X连锁型杜氏肌营养不良症携带者的身高、体重和小腿围，与32名年龄相仿的正常女性对照者进行了比较。尽管两组中左右小腿围之和对体重的回归均高度显著，但左右小腿围之差与体重、身高或年龄均无显著关联。通过协方差分析对体重进行校正前后，携带者与对照者的小腿围之和均无显著差异，两组在左右小腿围大小的不对称程度上也无显著差异。
