Recruitment Details
| Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations |
|---|
| PIVENS enrollment started in January 2005 and ended in January 2007. |
Pre-Assignment Details
| Significant events and approaches for the overall study following participant enrollment, but prior to group assignment |
|---|
| A total of 339 patients were registered and screened for PIVENS trial, 92 of whom (27%) were found ineligible. The failure to meet histological entry criteria and fasting blood glucose >125 mg/dL were the most frequent reasons for ineligibility. |
Reporting Groups
| Description | |
|---|---|
| Pioglitazone | Pioglitazone at a dose of 30 mg daily |
| Vitamin E | Vitamin E at a dose of 800 IU daily |
| Placebo | Placebo Pioglitazone and Placebo Vitamin E |

Total nonalcoholic fatty liver disease (NAFLD) activity score

5.0 ± 1.4 | 5.1 ± 1.4 | 4.8 ± 1.4 | 4.9 ± 1.4 |
| [1] | Total nonalcoholic fatty liver disease (NAFLD) activity was assessed on a scale of 0 to 8, with higher scores indicating more severe disease; the components of this measure include steatosis (assessed on a scale of 0 to 3), lobular inflammation (assessed on a scale of 0 to 3), and hepatocellular ballooning (assessed on a scale of 0 to 2). |
