Table 5. Cox regression analysis of overall mortality.

Variable	HR	SE	Wald	df	P-value	Exp(B)	95% CI Lower	95% CI Upper
The table presents the regression coefficients (B), standard errors (SE), Wald chi-square statistics, degrees of freedom (df), significance levels (P-values), hazard ratios (Exp(B)), and 95% CI for sarcopenic status, emergent PCI status, BMI > 30 kg/m2, and age. BMI: body mass index; PCI: percutaneous coronary intervention.
