What the evidence shows

The human evidence is split, and this verdict sits close to the boundary with contested: of five human rows, two randomised trials found no reduction in liver fat, one randomised trial and one observational study found one, and a meta-analysis came out mixed. Everything measured is a surrogate — MRI fat fraction and liver enzymes, not fibrosis or any clinical outcome.

meta-analysis contradicts low Jiao 2024, 10 RCTs / 578 NAFLD-NASH patients, ezetimibe 10 mg/d; only 1 of 10 control arms was placebo. LIVER FAT IS NULL ON EVERY ENDPOINT THE PAPER MEASURED: MRI-PDFF k=2/n=109, MD -2.44 (95% CI -5.25, 0.37), P=0.09, I2=0%; histologic steatosis k=2/n=67, MD 0.00 (-0.16, 0.16), P=1.00; NAS k=3/n=107, P=0.37; ballooning P=0.68; LSM k=2/n=120, P=0.91; fibrosis k=2/n=75, P=0.69. Authors' own summary: 'no marked improvements were noted in levels of ALT, TG, HDL, FPG, HOMA-IR, steatosis, or fibrosis'. The positive results are OFF-OBJECT for a liver-FAT claim - AST k=9/n=549 SMD -0.40, GGT k=6 SMD -0.49, but ALT NULL k=10/n=574 SMD -0.22 P=0.15 - plus TC, LDL-C, hs-CRP, IL-6; HbA1c ROSE (k=3/n=141, SMD +0.40, P=0.02). Null on a directional claim = contradicts (CONVENTIONS 5). The prior extract's 'improved liver fat/aminotransferases (heterogeneous)' fails on all three counts: fat was null, ALT was null, and the deciding MRI-PDFF pool had I2=0%. Quality low: the paper reports 8/10 trials with no allocation-concealment detail and 'more than half' with bias concerns, pools nine different comparators (diet, statins, acarbose, polyene phosphatidylcholine), and applies Egger's at k=2-4 against its own stated >=10-study rule; its abstract omits every liver-fat null. INDEPENDENCE (flagged, not fixed): the MRI-PDFF pool IS ESSENTIAL (Cho 2022) + MOZART (Loomba 2015), both of which vote separately on this claim; names them correctly.

2015 · Hepatology
RCT contradicts high MOZART randomised placebo-controlled trial, liver fat by MRI-PDFF across nine colocalised segments plus MR elastography: 'Ezetimibe was NOT significantly better than placebo at reducing liver fat' (between-arm mean difference -1.3%, p=0.4). Within-arm fat fell in the ezetimibe group (15%->11.6%, p<0.016) but not placebo (18.5%->16.4%, p=0.15) - a within-arm change without a between-arm difference is not an effect. Well-powered imaging null on a directional claim -> contradicts per CONVENTIONS 5.

Disagree, or know a study we missed?

We grade by evidence, not opinions. The way to weigh in is to point us to a study we haven't cited (check the evidence table above first), or to flag a problem with one we have. Every submission is reviewed; if it holds up, the grade updates and shows in Science Changes Its Mind.
