From: Auditory cortex hypoperfusion: a metabolic hallmark in Beta Thalassemia

  1. Pearson’s correlations between cognitive scores derived by the WAIS and right and left auditory/visual cerebral area perfusion ratio in healthy controls and patients. PRI Perceptual Reasoning Index, WMI Working Memory Index, PSI Processing Speed Index, VCI Verbal Comprehension Index. legend: red cells with upwards arrow = positive association with R > 0.2; pink cells with upwards arrow = trend of positive association with R > 0.2; blue cells with downwards arrow = negative association with R < − 0.2; ____ no association (− 0.2 < R < 0.2); significant p values are reported in bold
