Table 6. Kaplan–Meier Survival Analysis Stratified by Sarcopenia Status.

Cohort	Median Follow-up (days)	IQR (days)
Median follow-up was shorter in sarcopenic patients compared to non-sarcopenic patients. A log-rank test demonstrated a statistically significant difference in survival distributions between the two groups (χ2 = 6.13, P = 0.0133), indicating worse long-term survival among sarcopenic patients. IQR: interquartile ranges. This table summarizes the median follow-up times and interquartile ranges (IQR) for sarcopenic and non-sarcopenic patients, as well as for the overall cohort.
Sarcopenic	809.0	350.0–1403.0
Non-Sarcopenic	1244.0	518.5–1993.5
Overall Cohort	984.5	442.8–1845.5
Log-rank test	χ² = 6.13	P = 0.0133
