Comparison between patients with T2DM without vs. with 25-OH vitamin D deficiency.

*Differences are significanta Distributions are not Gaussian. Data is presented as median and [interquartile range]; p was calculated with Mann-Whitney U test.b Data is presented as mean±S; p was calculated with t-student test.c Data is presented as number and (percentage of total). p was calculated using chi-square test.Continuous variables distributions were tested for normality using Shapiro-Wilk test and for equality of variances with Levene’s test.Comparison between patients with T2DM without vs. with 25-OH vitamin D deficiency.* a. 差异具有统计学意义：数据分布不符合高斯分布。数据以中位数与[四分位数间距]的形式呈现，P值通过曼-惠特尼U检验（Mann-Whitney U test）计算。 * b. 数据以均值±S的形式呈现，P值通过t-student检验（t-student test）计算。 * c. 数据以例数及（总例数百分比）的形式呈现，P值通过卡方检验（chi-square test）计算。 连续变量的分布采用夏皮罗-威尔克检验（Shapiro-Wilk test）进行正态性检验，并采用莱文检验（Levene’s test）开展方差齐性检验。 本研究对比了无25-羟维生素D（25-OH vitamin D）缺乏的2型糖尿病（T2DM）患者与合并25-羟维生素D缺乏的2型糖尿病患者。
