The six-cluster solution grouping 159 subjects with schizophrenia, as produced by the k means cluster analysis. The four major clusters (1, 3, 4, and 5) comprise 153 subjects. Clusters 2 and 6 each contained less than 5% of the sample size, therefore they were considered outliers and dropped from analyses.
