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

The role of host genetic factors in the pathogenesis and outcome of hepatitis B virus (HBV) infection is not well known. We assessed the association of HLA and TNF (rs361525, rs1800629, rs1799724, rs1800630 and rs1799964) polymorphisms with HBV outcome in the South Indian population. Association of HLA polymorphism was analyzed in 90 individuals from each group, that is, spontaneous recovery (SR) and chronic-HBV (C-HBV) infection. The role of TNF polymorphisms was evaluated in 150 subjects with SR and 137 patients with C-HBV infection. After adjusting for age and sex, HLA-DRB1*07:01 was strongly associated with chronicity (corrected P-value (pc) <0.005, odds ratio (OR) 3.76, 95% confidence interval (CI) 1.84-7.68). The rs1800630 genotype was associated with HBV outcome in codominant (pc<0.01, OR=1.99, 95% CI 1.30-3.05) and dominant (pc<0.01, OR=2.28, 95% CI 1.35-3.84) analyzing models after adjusting for age and sex. Similarly, the rs1799964 genotype was associated with HBV outcome in codominant (pc=0.01, OR=1.57, 95% CI 1.09-2.27) and dominant (pc<0.01, OR=2.21, 95% CI 1.27-3.83) analyzing models. Haplotype analysis (rs1799964/rs1800630/rs1799724/rs1800629/rs361525) revealed that the CACGG haplotype was strongly associated with C-HBV infection (P=0.0004). Our study suggests that inheritance of HLA and TNF polymorphisms might explain the outcome of HBV infection in the South Indian population.
