Vitamin D status and related variables measured over 72 hours that may be associated with 30-day mortality.

Time trend p-value describes the change in the variable over the four measurement periods derived from a repeated measure ANOVA. Overall estimated mean is the least-square mean derived from a repeated measure ANOVA. †Results reflect analysis of the natural log transformed variables. Data are presented as mean ± standard error. 25(OH)D –25-dihydroxyvitamin D; 1,25(OH)2D –1,25-dihydroxyvitamin D; 24,25(OH)2D –24,25-dihydroxyvitamin D; PTH – parathyroid hormone.
