ALB and Hypertension: Table 1 illustrated apparent variations in baseline characteristics among the albumin quartiles. The study included 6,345 adults, with a mean (SE) age of 46.355 years. The serum albumin concentration was 42.594 g/L. Of these, 3292 participants were male, and 3053 were female. Individuals with higher albumin concentrations were more likely to be male, aged 20–34 years, married or cohabiting, with a BMI < 25, and without diabetes, hypertension, or nocturia (Table 1).
