The Mean age of each group of patients and the correlation with the Vitamin D levels

	Age (years±SD)	Vitamin D levels (ng/mL)	**P2	**r
Group 1	69.85±6.52	17.31±13.30	0.9	0.16
Group 2	69.47±9.26	13.34±7.87	0.035	-0.29
*P1	0.075	0.009

*P1 indicates the statistical significance level of the age and Vitamin D levels of group 1 and group 2 compared to the independent sample t test ** P2 and r represent statistical significance (P2) and correlation coefficient (r) in the Pearson correlation test of groups according to age and Vitamin D levels.
