<i>GABRB2</i> association in antipsychotics dosage-based SCZ subgroups.

Based on the average daily antipsychotics dosage of 5 mg fluphenazine equivalent, the US SCZ cohort (‘All’) was divided into ‘High dosage’ (>5 mg/day) and ‘Low dosage’ (≤5 mg/day) groups. The p-values were obtained from case-control association analysis using the likelihood ratio test. Significant p values (p<0.05) that passed the global permutation test are shown in bold font. The odds ratio (OR) and its 95% confidence level (CI) were based on allele frequencies.
