### Multiple Linear Regression Analysis for Independent Factors Determining CPI Scores  
Multiple linear regression analysis results for independent factors determining CPI scores are presented in Table 3. CPI scores were positively associated with PP in the overall population (\(\beta\), 0.128; 95% confidence interval (CI), 0.033 to 0.066) and HTN group (\(\beta\), 0.173; 95% CI, 0.034 to 0.087). However, CPI was positively associated with PP in the non-HTN group (\(\beta\), 0.041; 95% CI, \(-0.003\) to 0.045).
