Correlations between entropy and clinical features in patients. (A) This grid shows the correlation coefficients for patients between entropy z scores for pattern length m = 1:10 and chlorpromazine (CPZ) equivalents in addition to 5 symptom factors calculated from the Positive and Negative Syndrome Scale. These symptom factors are positive symptoms (POS), negative symptoms (NEG), disorganized symptoms (DIS), excited symptoms (EXC), and depressed symptoms (DEP). The red boxes indicate statistically significant correlations after correction for multiple comparisons. (B) Scatter plot showing the relationship between CPZ equivalents (in milligrams) and entropy z scores for pattern length m = 8. Note that the 3 unmedicated patients (red circles) all had z scores close to zero. The dashed gray line indicates a z score of zero. padj, Bonferroni-adjusted p value.
