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

objectiveTo perform a randomized controlled trial of rituximab in patients with hepatitis C virus (HCV)-associated mixed cryoglobulinemic vasculitis.

methodsWe conducted a single-center, open-label, randomized controlled trial of rituximab (375 mg/ m(2) /week for 4 weeks) compared to the best available therapy (maintenance or increase in immunosuppressive therapy) for HCV-associated cryoglobulinemic vasculitis in patients in whom antiviral therapy had failed to induce remission. The primary end point was disease remission at 6 months from study entry.

resultsA total of 24 patients were enrolled (12 in each treatment group). Baseline disease activity and organ involvement were similar in the two groups. Ten patients in the rituximab group (83%) were in remission at study month 6, as compared with 1 patient in the control group (8%), a result that met the criterion for stopping the study (P < 0.001). The median duration of remission for rituximab-treated patients who reached the primary end point was 7 months. No adverse effects of rituximab on HCV plasma viremia or on hepatic transaminase levels were observed.

conclusionRituximab was a well-tolerated and effective treatment in patients with HCV-associated cryoglobulinemic vasculitis in whom antiviral therapy failed to induce remission.
