[…] Data analysis was conducted using SigmaPlot for Windows, version 11.2 (Systat Software, Point Richmond, VA) and SPSS version 22 (IBM Corporation, Chicago, IL). The significance testing and reported probability values (P) were two-sided for all variables. A P value of ≤0.05 was defined as statistically significant. Continuous data were expressed as mean ± standard deviation. The normality of the distribution of the data was evaluated by the Shapiro-Wilk test. Differences between vitamin D depletion groups for continuous variables were analyzed using one-way analysis of variance with post hoc pair-wise multiple comparisons by the Student-Newman-Keuls test for normally distributed data or Kruskal-Wallis one-way analysis of variance with pair-wise multiple comparison by Dunn’s method for non-normally distributed data. Categorical data were evaluated by chi-square analysis. The paired t test or Wilcoxon signed rank test was used for comparing two simultaneous 25-OH vitamin D concentrations within the same set of patients. A preliminary bivariate correlation analysis of all collected categorical and quantitative variables for the presence of vitamin D deficiency was conducted to determine which covariates to use in the binary logistic regression analysis. Those variables that achieved a statistically significant trend of P ≤ 0.15 were used in the multivariate model. Odds ratio (OR) was expressed as mean with 95 % confidence intervals. […]
