Additional analyses of Wimberley et al. (2016b)'s data tested whether urbanicity (Wimberley et al., 2016a), the polygenic risk score for schizophrenia (PRS-SZ; Wimberley et al., 2017), functioning (Horsdal et al., 2017b), and C-reactive protein levels (Horsdal et al., 2017a) could predict TRS. The gene discussed is CRP; the disease is schizophrenia.
