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

backgroundVitamin D, beyond its role in calcium and bone metabolism, exhibits immunomodulatory effects on innate and adaptive immune pathways and is suggestively related to liver diseases.

objectiveThis study investigated the association of single-nucleotide polymorphisms in genes involved in vitamin D functions with hepatitis B virus (HBV) infection.

methodsFive hundred Chinese Han subjects, including 274 chronic HBV patients, 68 HBV infection resolvers, and 158 healthy controls without HBV infection, were studied. The CYP27B1-1260 promoter and the VDR Taq I polymorphisms were genotyped by polymerase chain reaction-restriction fragment length polymorphism.

resultsAlthough there was no difference between HBV patients and healthy controls, HBV patients and healthy controls had a higher frequency of the CYP27B1-1260 genotype CC (15.0% vs. 2.9%, p=0.004 and 13.3% vs. 2.9%, p=0.006, respectively) and allele C (38.3% vs. 25.7%, p=0.006 and 39.2% vs. 25.7%, p=0.006, respectively) compared with resolvers. The genotype and allele frequencies of the VDR Taq I polymorphism had no difference between patients, resolvers, and healthy controls.

conclusionThese results suggest that the CYP27B1-1260 promoter polymorphism is possibly associated with the persistence, but not susceptibility to HBV infection in Chinese HBV patients, and that the VDR Taq I polymorphism is not suggested to be related to chronic HBV infection.
