  2. F female, M male, PMI post-mortem interval, RIN RNA integrity, SCZ schizophrenia, CPZ chlorpromazine equivalent
  3. Data are mean ± s.d. Age and PMI ranges are in brackets. ^group sizes are different in the Protein Cohort inflammatory subgroups as we were unable to determine inflammatory biotype for some cases due to poor RNA quality/insufficient amplification of cDNA
