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
backgroundTriple therapy with telaprevir (TVR), pegylated interferon and ribavirin has improved antiviral efficacy in patients with chronic hepatitis C (CH-C). However, the severe adverse effects caused by TVR are important to resolve. In this prospective, randomized, multicenter, open-label study, the antiviral efficacy and safety in the reduced administration of TVR were examined.
methodsA total of 81 CH-C Japanese patients with HCV genotype 1 were randomized into two regimens of TVR 2250 mg (TVR-2250) or 1500 mg (TVR-1500) and treated with triple therapy for 24 weeks.
resultsThe mean HCV RNA at start, 2 and 4 weeks of treatment were 6.69 ± 0.70, 1.05 ± 0.74, 0.22 ± 0.48 log10 IU/ml in the TVR-2250 group and 6.70 ± 0.62, 1.02 ± 0.62, 0.13 ± 0.41 log10 IU/ml in the TVR-1500 group. The SVR rates were 85% in both groups (35/41 and 34/40, respectively). There were no patients with viral breakthrough in either group. As for adverse effects, rash more than moderate and severe anemia with <8.5 g/dl of hemoglobin were higher in the TVR-2250 group than in the TVR-1500 group (p = 0.046, p < 0.001, respectively). The increase in serum creatinine levels and decrease in estimated glomerular filtration rates were higher in the TVR-2250 group than in the TVR-1500 group.
conclusionsThe lower dose of TVR (1500 mg/day) can result in similar SVR rates and lower treatment-related adverse effects compared to the higher dose of TVR (2250 mg/day) in triple therapy (UMIN: 000007313, 000007330).
