Distribution of predicted outcome scores on the modified Rankin Scale[2]at three months over ordered vingtiles of a prognostic index for good outcome in the PAIS trial[1]. Six bands were defined in such a way that the median of the mRS in that band was equal to the next score on the mRS (1–6). Cut points were taken at quantile 7/8, 11/12, 14/15, 17/18, and 19/20.
