Notes: *Compared with control group, P<0.05. COPD prediction model equation and performance using the aforementioned five independent variables. The logit model to determine PRE_1 was expressed as follows: Logit(p) = -4.332 + (-2.406 BMI) + (-1.280 ALB) + (3.244 CCI score) + (2.840 GSRs score) + (3.237 GOLD classification); ; e: natural logarithm (~2.718); x= -4.332 + (-2.406 BMI) + (-1.280 ALB) + (3.244 CCI score) + (2.840 GSRs score) + (3.237 GOLD classification).

Abbreviation: NS, No statistical significance.
