mRS assessment: The denominator is the number of patients assessed for mRS at each evaluation time point. Changes from the preoperative assessment: The denominator is the number of patients assessed for mRS at both preoperative and the corresponding post-procedure time point (the sum of those classified as improved, unchanged, or worsened).
