| HR = 2.83 (1.55‐5.14) | HR = 2.35 (1.38‐3.99) | HR = 2.82 (1.51‐5.27) | HR = 1.76 (0.54‐5.68) | |
| >3 vs ≤3 cm | P = .009 | P = .064 | P = .139 | P = .043 |
| HR = 1.70 (1.13‐2.54) | HR = 1.38 (0.98‐1.95) | HR = 1.39 (0.90‐2.16) | HR = 1.91 (1.01‐3.62) | |
| >2 vs ≤2 cm | P = .169 | P = .136 | P = .054 | P = .081 |
| HR = 1.33 (0.89‐1.99) | HR = 1.28 (0.92‐1.78) | HR = 1.54 (0.99‐2.39) | HR = 1.86 (0.92‐3.78) |
Clinical outcome was described by Kaplan‐Meier plots of OS, DFS, DMFS, and RRFS P < 0.05 are highlighted in bold.
Abbreviations: CI, confidence interval; DFS, disease‐free survival; DMFS, distant metastasis–free survival; HR, hazard ratio; MAD, maximal axial diameter; OS, overall survival; RRFS, regional relapse–free survival.
