CEBPZ and autosomal dominant cerebellar ataxia: Across iWSAs, there was a discrepancy between sequences (Table 1; Figure 5); estimates based on the single-TI sequence indicated significantly higher mean CBF in patients with SCA with a large effect size (adjusted p < 0.001), whereas estimates based on the multi-TI sequence indicated non-significantly higher CBF in patients with SCA (adjusted p = 0.20).
