Dynamics of HBV biomarkers during nucleos(t)ide analog treatment: A 14-year study.
Article in Hepatology communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundCirculating HBsAg, HBV RNA, and hepatitis B core-related antigen (HBcrAg) are potential biomarkers for the response to nucleos(t)ide analog (NA) treatment discontinuation in patients with chronic hepatitis B (CHB). We retrospectively investigated the long-term kinetics of HBsAg, HBV RNA, and HBcrAg in HBeAg-negative patients treated with NA for up to 14 years in a prospective cohort study.
methodsNinety-six patients (mean age 65 y, 77% male, 52% with cirrhosis, all HBV genotype D) who were undergoing first (n=33, group A) or second-line (n=63, group B) treatment with tenofovir disoproxil fumarate were included. HBV biomarkers collected during tenofovir disoproxil fumarate treatment were measured in 384 serum samples stored at -20 °C. The combined biomarker endpoints associated with functional cure following NA discontinuation included HBsAg <1000 IU/mL, HBV RNA <54 copies/mL, and HBcrAg <2 log U/mL.
resultsBefore NA treatment, HBV RNA and HBcrAg were detectable in 85% (mean 3.9±2.3 [range, 0-9.2] log10 copies/mL) and 80% (mean 4.3±1.9 [2-8.9] log10 U/mL), respectively, of the patients in group A. In groups A and B, the percentages of patients with detectable HBV RNA levels decreased to 53% and 34%, respectively, during years 8-10 of NA treatment, and to 29% in group B during years 11-14 to 29%. HBcrAg could be quantified in 2% of patients in group B NA treatment years 8-10. Combined biomarker endpoints were met at baseline and at years 1-4, 5-7, 8-10, and 11-14 of treatment by 3.3%, 12% and 14%, 13% and 38%, 26% and 29%, and 41% of patients, respectively.
conclusionsHBV biomarker endpoints are associated with functional cure after the discontinuation of NA increase during long-term NA treatment.
