The effects of two vitamin D regimens on ulcerative colitis activity index, quality of life and oxidant/anti-oxidant status

Table 5 Mean and standard deviation score of quality of life and clinical activity score in patients participated in two groups taking high and low doses of vitamin D at the beginning and end of the study

Variables	Time of the study
Variables	Beginning of study	End of study	P-value^c	^aP-value	^bP-value
Quality of life questionnaire score				0.001	0.003
Low dose group	42.59 ± 8.66	44.73 ± 8.01	< 0.001
High dose group	40.54 ± 9.46	46.75 ± 9.27	< 0.001
P-value^d	0.45	0.43
Clinical Activity Indicator Questionnaire score				0.004	0.045
Low dose group	3.00 ± 3.59	2.68 ± 2.27	0.009
High dose group	5.25 ± 2.98	2.67 ± 2.25	< 0.001
P-value^d	0.06	0.98

The values are reported as mean ± standard deviation
^aP –value for complementary efficacy (changes comparison) by Student T-test
^bP-value for complementary efficacy (changes comparison) after adjustment by ANCOVA test for BMI, and baseline values
^cP –value for within group comparison using paired t test
^dP –value for between groups comparison using Student T-test
