Abstract

BACKGROUND: Nonalcoholic steatohepatitis is a common liver disease that can progress to cirrhosis. Currently, there is no established treatment for this disease. METHODS: We randomly assigned 247 adults with nonalcoholic steatohepatitis and without diabetes to receive pioglitazone at a dose of 30 mg daily (80 subjects), vitamin E at a dose of 800 IU daily (84 subjects), or placebo (83 subjects), for 96 weeks. The primary outcome was an improvement in histologic features of nonalcoholic steatohepatitis, as assessed with the use of a composite of standardized scores for steatosis, lobular inflammation, hepatocellular ballooning, and fibrosis. Given the two planned primary comparisons, P values of less than 0.025 were considered to indicate statistical significance. RESULTS: Vitamin E therapy, as compared with placebo, was associated with a significantly higher rate of improvement in nonalcoholic steatohepatitis (43% vs. 19%, P=0.001), but the difference in the rate of improvement with pioglitazone as compared with placebo was not significant (34% and 19%, respectively; P=0.04). Serum alanine and aspartate aminotransferase levels were reduced with vitamin E and with pioglitazone, as compared with placebo (P<0.001 for both comparisons), and both agents were associated with reductions in hepatic steatosis (P=0.005 for vitamin E and P<0.001 for pioglitazone) and lobular inflammation (P=0.02 for vitamin E and P=0.004 for pioglitazone) but not with improvement in fibrosis scores (P=0.24 for vitamin E and P=0.12 for pioglitazone). Subjects who received pioglitazone gained more weight than did those who received vitamin E or placebo; the rates of other side effects were similar among the three groups. CONCLUSIONS: Vitamin E was superior to placebo for the treatment of nonalcoholic steatohepatitis in adults without diabetes. There was no benefit of pioglitazone over placebo for the primary outcome; however, significant benefits of pioglitazone were observed for some of the secondary outcomes.

  • In the PIVENS trial, 47% with Pioglitazone versus 21% with placebo showed resolution of definite NASH (p = 0.001).

    “47% with Pioglitazone versus 21% with Placebo showed a resolution of definite NASH (p = 0.001) [33].”

    From Current treatment of non‐alcoholic fatty liver disease (2022) · cites this paper as [33]

    The Results (Secondary Outcomes) report that steatohepatitis resolved significantly more often with pioglitazone than with placebo (P = 0.001), and the Discussion gives a 47% resolution rate for pioglitazone. The passages in our copy do not give the claimed 21% placebo resolution rate; the 19% placebo figure in Primary Outcome refers to a different measure, histologic improvement. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • In the PIVENS trial, adverse events in the Vitamin E group were not significantly different compared to Pioglitazone or placebo.

    “adverse events in the Vitamin E group were not significantly different compared to Pioglitazone or placebo [33].”

    From Current treatment of non‐alcoholic fatty liver disease (2022) · cites this paper as [33]

    The Results (Secondary Outcomes, Adverse Events) say the distribution of individual adverse events did not differ significantly across the three groups, except for weight gain. The claim omits that exception: the Results also report significant weight gain in the pioglitazone group. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • In the PIVENS trial, the grade of fibrosis did not improve with Vitamin E.

    “However, the grade of fibrosis did not improve [33].”

    From Current treatment of non‐alcoholic fatty liver disease (2022) · cites this paper as [33]

    The Results (Secondary Outcomes) say fibrosis scores were not significantly improved with vitamin E. The Discussion likewise reports no significant improvement in mean fibrosis score after 96 weeks. These passages support a lack of demonstrated improvement, but not the stronger statement that fibrosis did not improve at all. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • In the PIVENS trial, fibrosis was not affected by Pioglitazone treatment.

    “Similar to the Vitamin E treatment arm, fibrosis was not affected by Pioglitazone treatment [33].”

    From Current treatment of non‐alcoholic fatty liver disease (2022) · cites this paper as [33]

    The Results (Secondary Outcomes; page not provided) say fibrosis scores were not significantly improved with either pioglitazone or vitamin E. The Discussion likewise reports no significant improvement in mean fibrosis score after 96 weeks. This supports a lack of demonstrated benefit, but “was not affected” overstates the finding by implying that treatment had no effect. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • In the largest RCT to date, vitamin E supplementation (800 IU daily over 2 years) in individuals with non-diabetic MASH resulted in improvements in both steatosis and disease activity, corroborated by a reduction in liver enzymes.

    “In the largest RCT to date, vitamin E supplementation (800 IU daily over 2 years) in individuals with non-diabetic MASH resulted in improvements in both steatosis and disease activity, which was corroborated by a reduction in liver enzymes.”

    From EASL-EASD-EASO Clinical Practice Guidelines on the management of metabolic dysfunction-associated steatotic liver disease (MASLD). (2024) · cites this paper as [372]

    The Methods report 247 adults without diabetes randomized to 800 IU of vitamin E daily or other treatment for 96 weeks. The Results report improvements in steatosis and disease activity versus placebo, alongside reduced liver-enzyme levels. The paper describes earlier trials as small but does not establish that this was the largest RCT to date. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
