Outcomes
Primary outcome [1] 0 0
modified Rankin Scale
Assessment method [1] 0 0
Neurological outcome was assessed by the modified Rankin scale (mRS), and a favorable neurological outcome was defined as mRS 0, 1, or 2. The scale runs from 0 to 5, and higher scores mean a worse outcome.
Timepoint [1] 0 0
Within 24 hours of admission to discharge, assessed up to 30 days
Primary outcome [2] 0 0
Sensorimotor neurological deficits
Assessment method [2] 0 0
Any new sensorimotor neurological deficits after surgery will be captured.
Timepoint [2] 0 0
Within 24 hours of admission to discharge, assessed up to 30 days
Primary outcome [3] 0 0
Clavien Dindo Complication Grading
Assessment method [3] 0 0
Complications will be assessed using the modified 2009 Clavien-Dindo grading (CDG), and occurrence of a complication was defined as any deviation from CDG 0. The CDG runs from 0 to 5, and higher scores mean a worse complication.
Timepoint [3] 0 0
Within 24 hours of admission to discharge, assessed up to 30 days
