1 · What the graph read from it

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.

2 · The registry

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

Occult hepatitis B virus infection (OBI), characterized by detectable HBV DNA but undetectable HBsAg, poses diagnostic and clinical challenges, with host genetic factors, particularly HLA-mediated immune regulation, remaining poorly understood. Through whole-exome sequencing of 147 participants (74 OBI cases, 73 chronic HBsAg + controls), we identified four HLA single nucleotide polymorphisms (SNPs) associated with low OBI susceptibility and proposed a dual immune mechanism: Class I SNPs impair cytotoxic responses, while Class II SNPs dysregulate humoral immunity. Anti-HBs titers and age modulated genetic risk penetrance, with high anti-HBs increasing OBI susceptibility regardless of genotype, and genetic effects attenuating in individuals > 50 years. Integrating HLA genetic markers with serological and baseline characteristics significantly improved OBI susceptibility prediction (AUC 0.93), highlighting the role of HLA-mediated immunity in OBI pathogenesis and the potential of genetic markers for risk stratification in HBV-exposed individuals. Our findings elucidate HLA-mediated immune mechanisms underlying OBI and demonstrate the value of genetic markers in predicting the likelihood of developing OBI or progressing to chronic HBsAg + status among HBV-exposed individuals.
