Changes in Three-Dimensional Volumetric Liver Fat Fraction after Cure of Chronic Hepatitis C Infection With Direct-Acting Antivirals.
Article in Open forum infectious diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: It remains unclear if cure of hepatitis C virus (HCV) infection with direct-acting antivirals (DAAs) leads to change in liver fat fraction and if this change differs from people without HCV observed over similar time. We evaluated the change in three-dimensional volumetric liver fat fraction by magnetic resonance imaging (MRI) prior to DAA treatment and 18 months following initiation and compared changes in uninfected controls over 18 months. Methods: We conducted a cohort study of 35 participants who initiated DAAs and achieved cure and 42 without HCV infection as controls. At enrollment and 18 months later, participants had measurements of height, body weight, and three-dimensional volumetric liver fat fraction and cross-sectional area of abdominal subcutaneous and visceral adipose tissue by MRI. Multivariable linear regression was used to estimate group differences in mean changes in liver fat fraction. Results: Mean change in three-dimensional volumetric liver fat fraction between Months 0 and 18 was +2.89% (95% CI: +.89%, +4.88%) among participants with cured HCV and +0.48% (95% CI: -1.02%, +1.97%) among controls (between group difference Conclusions: Three-dimensional volumetric liver fat fraction by MRI significantly increased between Months 0 and 18 following successful treatment of HCV infection, but this finding was not observed from Month 0 to 18 among participants without HCV infection.
