Demographic data were obtained for 3 health state profiles:
(1)Mild (n=43): average age = 34.2; 69.8% men; age at onset of schizophrenia = 20.5; age at first hospitalisation = 21.9; number of hospitalisations = 5.6;
(2)Moderate (n=60): average age = 38.5; 75.0% men; age at onset of schizophrenia = 21.4; age at first hospitalisation = 23.4; number of hospitalisations = 7.4;
(3) Severe (n=27): average age = 38.3; 67.7% men; age at onset of schizophrenia = 19.9; age at first hospitalisation = 21.8; number of hospitalisations = 7.1.
No power calculations were stated, although the authors referred readers to the previous paper for more information on data distribution.
