Distribution of all identified Claudin14 SNPs in the low and high urinary Ca2+ excretion groups with unadjusted Chi square P values.

The missense variant rs113831133, highlighted in bold, was more frequent among individuals with lower urinary Ca2+ excretion. This association did not reach statistical significance when adjusted for multiple comparisons.以粗体标注的错义变异（missense variant）rs113831133在尿钙排泄量较低的个体中出现频率更高。该关联在校正多重比较后未达到统计学显著性。
