ALB and Cognitive impairment: Figure 6B illustrates the volcano plot graphs showing the associations of the demographic (square), kidney function (eGFR; diamond), complete blood count (triangle), and biochemical data (circle) with risk of cognitive impairment. In the univariate analysis (left; model 1), 1-standard deviation (S.D.)increases in eGFR (18.7 mL/min/1.73 m2), WBC (1,894/μL), hemoglobin (2.26 g/dL), serum albumin (0.64 g/dL), and BMI (4.13 kg per m2) were associated with a lower risk of cognitive impairment.
