From: The effect of sunlight exposure on interleukin-6 levels in depressive and non-depressive subjects
A- Levels of IL-6 in relation to BDI scores (including the depressive and non-depressive groups). B- Comparison of IL-6 levels between two groups: high exposure sunlight group (HEL) and low exposure sunlight group (LEL) in non-depressive subjects. C- Comparison of IL-6 levels between the HEL and LEL groups in depressive subjects. The Student’s t-test for independent samples was used to analyze the mean differences between groups. IL-6 = interleukin; IL-6 levels are shown in pg/ml. *p < 0.05.
