Distribution of scores in the modified Rankin scale at 90 days after IAMT for each group. Score distribution in both groups was unequal, in a significant way: 60.6% of cases with mRS ≥ 4 and 70.6% with mRS ≥ 3 were observed in the hyperoxia group, in comparison with 43.0% and 56.1%, respectively, observed in paO2 < 120 group, p < 0.01. Mortality was higher in the hyperoxia group, 28.6% vs 18.7%, p = 0.04
