Serum high-sensitivity CRP (hs-CRP), fibrinogen, erythrocyte sedimentation rate (ESR), and uric acid (UA) in males according to OSA (obstructive sleep apnea) severity. (a) Serum hs-CRP is found elevated only in severe compared to mild OSA patients but not in control, mild, or moderate OSA patients. ∗p = 0.001 versus mild group. (b) Serum fibrinogen is found elevated in severe and moderate compared to mild OSA patients but not in control and mild OSA patients. ∗p = 0.02, ∗∗p = 0.001 versus mild group. (c) ESR levels are significantly different between all groups, apart from mild versus moderate (p = 0.98) and moderate versus severe groups (p = 0.06). ∗p < 0.05 versus mild, moderate, and severe groups. ∗∗p < 0.05 versus control and severe groups. #p < 0.05 versus control. §p < 0.05 versus control and mild groups. (d) UA levels are significantly elevated in severe compared to control, mild, and moderate groups. ∗p < 0.001 versus severe group. ∗∗p < 0.001 versus severe group. #p < 0.05 versus severe group. §p < 0.05 versus control, moderate, and severe groups.
