hs‐CRP, high‐sensitive C reactive protein was evaluated using nephelometric method; IQR, interquartile range.
Kruskal–Wallis test, P = 0.0180. The categories of 51–60 and ≥61 years were evaluated together (n = 19). Dunn's test, PCR values from individuals with 18–25 years differed from those individuals with 26–30 and with 41–50 years old.
Mann–Whitney test, P < 0.0001.
Non‐Caucasian, Asiatic (n = 5, 2.8%), black (n = 9, 5.2%) and Mullato (n = 20, 11.3%); Mann–Whitney test, P = 0.5689.
BMI, body mass index was evaluated in 172 individuals; Kruskal–Wallis test, P = 0.0005; Dunn's test, the group with BMI 18.5–24.9 kg/m2 differed from those with BMI 30.0–34.9 kg/m2.
