Analyzing the baseline examination data in univariate analysis, an increasing baseline SBP was associated with older age (P < 0.001), higher proportion of men (P < 0.001), lower level of education (P < 0.001), higher prevalence of ever smoking (P < 0.001), higher body mass index (P < 0.001), higher serum concentrations of total cholesterol (P < 0.001), low-density lipoproteins-C (P < 0.001), glucose (P < 0.001), C-reactive protein (P < 0.001) and uric acid (P < 0.001), higher prevalence of prediabetes, and lower eGFR (Table 1). Here, CRP is linked to prediabetes syndrome.
