在JAMA上的一篇文献中看到这么一句话：We used multiple logistic regression analysis to assess the independent effects of a woman's own birth weight, gestational age, and other factors on the development of GDM, and to determine the influence of potential confounders. To evaluate the effects of birth weight adjusted for gestational age on GDM risk, we included gestational age as a covariate in the multiple logistic regression model; we assessed the influence of gestational age adjusted for birth weight in the same manner.

加粗的部分，在写sas代码的时候，为什么感觉是一样的，协变量的顺序不一样也会影响结果吗?有大神能帮忙解释一下吗?谢谢谢谢！
