Clinical and biochemical characteristics of PCOS patients and non-hyperandrogenic control women.

Results are means±SD or raw numbers and percentages. Continuous variables were submitted to a general linear model in which age was introduced as a covariate to correct for the difference in age observed between patients and controls. Categorical variables were submitted to Fisher's exact test.结果以均值±标准差（SD）或原始数值及百分比形式呈现。连续变量采用一般线性模型（general linear model）进行分析，以年龄作为协变量，校正患者与对照组间观测到的年龄差异。分类变量则采用Fisher精确检验（Fisher's exact test）进行分析。
