Cut points for the Neuro-QoL Item Bank v2.0—Cognitive Function. NQ-Cog = Neuro-QoL Item Bank v2.0—Cognitive Function. Vignettes are shown by their associated T score (M = 50, SD = 10), where a T score equal to 50 matches the mean of that measure’s reference sample. For the NQ-Cog, that reference sample matches a U.S. census-matched general population [53]. Each colored cell represents how each group classified each vignette (e.g., the T25 vignette, the T30 vignette)—within normal limits (blue), mild (yellow), moderate (orange), or severe (red). The synthesized cut points, determined by the adjudicating expert panel, are at the bottom
