Hemorrhage alone was not significant, but the hemorrhage × depth interaction approached significance ( p = 0.078), suggesting a possible mitigating effect.

Furthermore, certain patient-related risk factors such as emphysema or aberrant pulmonary function did not reach statistical significance in our model, whereas prior studies have reported discordant findings for these variables [ 18 , 19 ].
