The modified Rankin Scale (mRS) score measures degree of disability (score range, 0 [symptom free] to 6 [death]). The proportion of patients who achieved functional independence at 3 months (mRS score of 0-2) was lower in the intensive management group (39.4%) than in the conventional management group (54.4%) (adjusted odds ratio, 0.56 [95% CI, 0.33-0.96]; P = .03). The mRS shift analysis also showed that the intensive management group had worse scores than the conventional management group (adjusted odds ratio, 0.65 [95% CI, 0.43-0.97]; P = .04).
