Comparison of interpersonal trait and vector length T-scores between different clinical stages in the SemD group. A random coefficient model (univariate model) using SAS Proc Mixed was used to generate estimates of interpersonal trait and vector length T-scores at different clinical stages, adjusting for age and gender. Values are listed as estimates (standard error).

Bold type signifies a score which fell more than 1.5 SD from the mean, i.e., scores below 35 or above 65.
