Serum hepatitis B virus RNA in low-level viremia of chronic hepatitis B: clinical features and association with virological response.

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
backgroundThe role of hepatitis B virus (HBV) RNA in the management of patients with chronic hepatitis B (CHB) experienced with low-level viremia (LLV) remains poorly defined. This study was designed to evaluate the prognostic utility of serum HBV RNA as a biomarker for predicting treatment outcomes in this population.
methodsA retrospective cohort analysis was conducted on 117 pediatric patients with LLV (mean age: 13.14 years; 34% female) treated with continuous entecavir (ConT) or modified regimens (switching to or combining with tenofovir disoproxil fumarate) for ≥ 120 weeks. Virological response was defined as HBV DNA < 10 IU/mL at week 120.
resultsNo significant baseline differences existed between ConT and modified regimen groups. Compared to ConT, modified regimens achieved greater reductions in serum HBV DNA, HBV RNA, and quantitative HBsAg, with higher cumulative undetectable rates at week 120 (HBV DNA: ≥ 80.0%; HBV RNA: ≥ 54.8%; P < 0.05). Notably, qHBsAg levels remained elevated in most patients, with only 3 individuals achieving undetectable levels (< 0.05 IU/mL). Multivariate analysis identified higher HBV RNA levels at week 48 as an independent risk factor for non-virological response (adjusted odds ratio: 5.86; 95% confidence interval: 1.40-24.62; P = 0.016). Although HBV RNA alone was less predictive than HBV DNA (area under the receiver operating characteristic curve [AUC]: 0.76 vs. 0.80; P = 0.459), combining both markers improved prediction accuracy (AUC: 0.82; P < 0.05 vs. single markers).
conclusionsIn children with LLV, serum HBV RNA level is an independent risk factor for non-virological response and may serve as a complementary biomarker to HBV DNA for guiding antiviral therapy adjustments.
