PRIMARY outcome

Timeframe: pre-treatment and during 3 months of treatment

Population: Data is from participants at U.S. sites N=44, Pioglitazone =25, Placebo =19, who had values of triglycerides at baseline and three months followup. See table 2 of published paper given in reference for further details.

Population: Data is from participants at U.S. sites N=44, Pioglitazone =25, Placebo =19, who had values of serum glucose at 2-hour point in glucose tolerance test at baseline and three months follow-up. See table 2 of published paper and its supplementary data paper cited in reference for further details.

SECONDARY outcome

Timeframe: pre-treatment and 3 months of treatment

Population: Data is from participants at U.S. sites N=43, Pioglitazone =25, Placebo =18, who had scores of RBANS List learning at 2-hour point at baseline and three months follow-up. See table 2 of published paper and its supplementary data paper cited in reference for further details.

The scale is Repeatable Battery for the Assessment to Neuropsychological Status (RBANS). This scale measure cognitive function in patients with schizophrenia. Range for list learning sub-score is 0 to 20 . Higher values indicate better performance. For change score (3 months -baseline) positive values indicate improved performance for this cognitive function and negative values indicate poorer performance on this cognitive function.
