Relationship between change in IEQ total score and baseline characteristics (continuous variable)

Baseline characteristics	Estimated slopea	p valuea
Patient age	0.106	0.0226
Patient age at diagnosis of schizophrenia	0.029	0.6211
Number of psychiatric hospitalizations within past 24 monthsb	−1.026	0.0633
Duration of latest psychiatric hospitalizations (days)	0.002	0.5371

^a An ANOVA model was fitted with IEQ total score change at end point (DB) from baseline (OL) as the outcome variable, and Study ID as a factor. In addition, variables for baseline characteristics were included in the model as a factor one at a time

^b For patients with number of hospitalization recorded as “ ≥ 4”, the value was changed to be 4 so that the model would consider “number of hospitalization” as numeric
