In addition, S100B serum concentration plotted against BMI showed a statistically significant correlation (Pearson’s correlation; r = 0.4868; p value (two tailed) = 0.0117) in female patients with schizophrenia, treated with clozapine (Figure 5C) but was not correlated in the male patient group (Pearson’s correlation; r = −0.2395; p value (two tailed) = 0.0511) (Figure 5B). The gene discussed is S100B; the disease is schizophrenia.
