Trial Outcomes & Findings for Edaravone-Sodium Ozagrel Comparative Post-Marketing Study on Acute Ischemic Stroke (NCT NCT00200356)

NCT ID: NCT00200356

Last Updated: 2026-01-07

Results Overview

The number of patients with mRS score of 0-1 (good outcome) at 3 months after treatment initiation. The mRS has 6 items, where 0 = No symptoms at all, 1 = No significant disability despite symptoms, 2 = Slight disability, 3 = Moderate disability, 4 = Moderately severe disability, 5 = Severe disability. The higher scores reflect increased disability.

SECONDARY outcome

Timeframe: 3 months

The Barthel Index of Activities of Daily Living measures functional disability by quantifying patient performance in 10 activities of daily life. These activities can be grouped according to self-care (feeding, grooming, bathing, dressing, bowel and bladder care, and toilet use) and mobility (ambulation, transfers, and stair climbing). 5-point increments are used in scoring, with a maximal score of 100 indicating that a patient is fully independent in physical functioning, and a lowest score of 0 representing a totally dependent bed-ridden state. The number of patients with 95-100 Barthel Index was evaluated at at 3 months after treatment initiation.
