Table 1 represented the baseline demographic and clinical data of the studied cohort by BMI category. In the entire cohort, overweight and obese subjects were more likely to be older and had higher proportion of diabetes, as compared with normal weight individuals. There was a trend towards higher levels of TG, hs-CRP, and rGFR with increased BMI values (all p < 0.001), whereas BMI categories were inversely related to total Kt/Vurea (p < 0.001). This evidence concerns the gene CRP and diabetes mellitus.
