Figure 1 Distribution of PANSS total scale scores for affected and unaffected subjects, under the narrow diagnostic classification of schizophrenia. The numbers of affected subjects (gray-shaded bars) and unaffected subjects (unshaded bars), with values for each of the PANSS scales, are presented for the (a) positive symptom–scale, (b) negative symptom–scale, and (c) GP symptom–scale scores of PANSS, which have minimum possible values of 7, 7, and 16, respectively.
