↵a Parameter estimates (standard error when applicable) from a linear fixed-effects model reported relative to normalized time since stroke onset (defined at initiation of scanning 1 hour following stroke induction).
↵b Indicates statistical significance at P < .05, results of 2-tailed t test of F-statistics.
