Nutritional status of elderly hypertensive patients and its relation to the occurrence of cognitive impairment

Figure 2 Development of a column-line diagram model for predicting cognitive impairment in elderly hypertensive patients. A: Column line diagram. R software quantified modeling cohort of 140 elderly hypertensive patients with cognitive impairment risk coefficient; B: Modeling queue calibration curves. R software was used to perform curve correction on the cognitive impairment model of 140 elderly hypertensive patients in the modeling cohort (mean absolute error = 0.042); C: Modeling queue receiver operating characteristic curve. R software was used to analyze the receiver operating characteristic curve of the model of cognitive impairment in 140 elderly hypertensive patients in the modeling cohort, and the area under the curve was 0.921; D: Modeling queue decision analysis curve. R software decision curve analysis was used to evaluate the discriminant ability of the model of cognitive impairment in 140 elderly hypertensive patients in the modeling cohort. BMI: Body mass index; ALB: Albumin; Hb: Hemoglobin; ALP: Alkaline phosphatase; MNA: Mini-Nutritional Assessment Scale; AUC: Area under the curve.
