In contrast, the rDOI exhibited only a trend toward significance ( p = 0.087), with a median of 13 mm (95% CI: 10–17) in patients with recurrence and 11 mm (95% CI: 8–13) in those without.

The hazard ratios of the included variables are reported in Table 4 : patients with a positive pN status had an increased risk of at least 3-fold of developing a loco-regional recurrence compared to patients with pN0; the radiological dimension of the lesion and rDOI were marginally statistically significant, showing a very small effect size; the type of surgery indicated that patients who underwent a transoral surgery plus neck dissection had a better outcome compared to patients receiving a pull-through surgery plus neck dissection, even though on the threshold of statistical significance.
While the smoking status did not show a statistically significant difference between patients with and without recurrence, alcohol consumption and surgical approach showed a trend toward significance, even though they were not included in the final classification models.
