SOPS, Scale of Prodromal Symptoms; CNTL, healthy comparison subjects; CHR+NT, CHR+ subjects who did not transition to psychosis; CHR+T, CHR+ subjects who did transition to psychosis.

SOPS total scores are presented along with the standard error of the mean in parentheses and are estimated marginal means derived from the linear mixed models.
