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
BACKGROUND &
objectivesThe effect of vitamin D supplementation on response to antiviral therapy in hepatitis C virus (HCV) genotype 1 and 4 infection still remains unclear, with studies yielding inconsistent results. The aim of the present study was to assess the effect of vitamin D supplementation on treatment outcome in patients with genotype 1/4 chronic hepatitis C (CHC) infection.
methodsSixty consecutive, treatment-naïve, genotype 1 and 4 chronic HCV patients were included in the study. The patients were randomized into two groups: Vitamin D supplemented group received pegylated (PEG)-interferon α-2a 180 μg per week plus ribavirin (RBV) (1000-1200 mg/d) together with vitamin D3 (2000 IU/d) and control group received identical therapy without vitamin D (32 patients).
resultsThere were no significant differences between the two groups in terms of age, sex, body mass index and baseline laboratory values. Lower vitamin D levels were associated with higher grades of fibrosis in liver histology (vitamin D >20 ng/ml - 70% vs vitamin D <20 ng/ml - 37%, P<0.05). Vitamin D supplemented group had similar rapid viral response (40 vs 28%, P=0.36), complete early viral response (53.2 vs 40%, P=0.34), end of treatment response (64 vs 46%, P=0.17) and sustained virological response (SVR) (60 vs 44%, P=0.19) as compared to control group. Interleukin 28B polymorphism [odds ratio (OR)-15.37, 95% confidence interval (CI)-2.32-101.76, P=0.04] and baseline serum vitamin D levels (OR-6.36, 95% CI-1.36-29.61 P=0.02) were independent predictors of SVR in genotype 1/4 CHC. Vitamin D supplementation was not found to be predictor of response in genotype 1/4 CHC on multivariate analysis (OR-2.79, 95% CI- 0.63-12.34, P=0.74). INTERPRETATION &
conclusionsThe present study showed that addition of vitamin D to PEG/RBV combination therapy in treatment-naïve patients who were infected with HCV genotype 1/4 had no effect on the rates of rapid, early and sustained viral responses.
