Figure 1: Correlation between Uca/Ucr and 25-hydroxyvitamin D. Line shows the least-squares line. Left panel, data for all subjects. There is no correlation between Uca/Ucr and 25-hydroxyvitamin D (n=58, r2=0.030, p is ns). The outlier was a subject found to have idiopathic hypercalciuria. Right panel, subjects with 25-hydroxyvitamin D <80 nmol/L. There is no correlation (n=17, r2=0.045, p is ns).
