  2. Pearson correlations between 5C-CPT and CPT-IP d′s, MCCB composite (without the CPT-IP included), subscale T-scores, and SANS and SAPS total scores. Statistical significance (*) was determined based on a Bonnferoni correction, which required p < 0.004. Plus symbol (+) indicates corrected trend-level significance p < 0.01. Right column depicts p-values for Fisher-z correlation comparisons between left and middle columns using single-sided testing
