Correlation between CD4+ T cells, serum iron and antioxidants in test subjects
Parameters CD4+T cell count
Correlation P -value
Vitamin C (μmol/l) r = 0.497 P <0.001*
Zinc (μmol/l) r = 0.737 P <0.001*
Selenium (μmol/l) r = 0.639 P < 0.001*
Serum Iron (μmol/l) r = − 0.572 P < 0.001*

r values denotes degree of positive or negative correlation.

P value < 0.05 is statistically significant.

*P denotes significant positive or negative correlation.
