  Figure 1.. Serum index. All statistical serum index data in this study were entered into excel software by the first author and corresponding author respectively, and the statistical processing software was SPSS 25.0 for calculation. An independent sample t test analysis was performed between the 2 groups to measure the measured values expressed as mean ± standard deviation. It was found that ALB, TC, TG, LDL-C, HDL-C, and CR levels in the serum of the 3 groups of patients were compared by one-way ANOVA. The serum ALB and HDL-C levels in the frailty group and the pre-frailty group were significantly lower than those in the non-frailty group, and the difference was statistically significant (all P < .05) (Fig. 1A–E). The serum TC, TG, LDL-C, and CR in the frailty group, pre-frailty group, and non-frailty groups were no significant difference (all P > .05) (Fig. 1B–D and F). *P < .05 compared with the non-frail group. ALB = albumin, ANOVA = analysis of variance, CR = creatinine, HDL-C = high-density lipoprotein, LDL-C = low-density lipoprotein, TC = total cholesterol, TG = triglyceride.

  Figure 2.. Blood pressure level. All statistical blood pressure level data in this study were entered into excel software by the first author and corresponding author respectively, and the statistical processing software was SPSS 25.0 for calculation. An independent sample t-test analysis was performed between the 2 groups to measure the measured values expressed as mean ± standard deviation. The 24-hour systolic blood and diurnal systolic blood pressure in the frailty group and the pre-frailty group were significantly lower than those in the non-frailty group, and the difference was statistically significant (all P < .05) (Fig. 1A and C). It was found that comparing the 24-hour diastolic blood pressure, daytime diastolic blood pressure, nighttime systolic blood pressure, and nighttime diastolic blood pressure between the frailty group, pre-frailty group, and non-frailty group, there was no statistical significance (all P > .05) (Fig. 2B and 2D–F). *P < .05 compared with the non-frailty group.
