While the favorable LabPS score group consistently exhibited numerically longer mean MFS times of 117.61 months (95% CI: 104.95–130.26; median not reached) compared with the unfavorable group (MFS mean: 99.97 months; 95% CI: 87.32–112.62; median not reached), the difference in MFS distributions between the 2 score groups did not reach statistical significance according to the log-rank test ( P = .691).
