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

backgroundPilot studies of interferon alpha (IFN-alpha) suggest a high remission rate in the treatment of active ulcerative colitis. We evaluated the safety of pegylated interferon alpha (PegIFN) and its role in induction of remission in patients with active ulcerative colitis, in a multicentre placebo controlled trial.

methodsSixty patients with a clinical activity score (CAI) of >6 were randomised to receive placebo (n=20), PegIFN 0.5 microg/kg (n=19), or PegIFN 1.0 microg/kg body weight (n=21) once weekly (PegIntron; Schering-Plough, USA) over 12 weeks. Patients receiving 5-aminosalicylates, steroids, and/or azathioprine in stable dosages were included.

resultsSerious adverse events were seen in none of the placebo patients, in 3/19 patients in the PegIFN 0.5 microg/kg group (hospitalisation due to disease flare up n=3), and in 3/21 in the PegIFN 1.0 microg/kg group (hospitalisation due to disease flare up n=1; thrombosis n=1; grand mal seizure n=1). Otherwise, we observed only minor IFN-alpha side effects. Clinical remission rates at week 12 (CAI < or =4) were 7/20 (35%) in the placebo, 9/19 (47%) in the PegIFN 0.5 microg/kg group, and 7/21 (33%) in the PegIFN 1.0 microg/kg group (NS). Early withdrawal from the study was observed in 11/20 placebo patients, in 6/19 in the PegIFN 0.5 microg/kg group, and in 10/21 in the PegIFN 1.0 microg/kg group, mainly due to lack of efficacy. The higher PegIFN dose was associated with a significant decrease in levels of C reactive protein (p=0.003, day 0 v 85).

conclusionsPegIFN is safe but not effective, at the dosages used, in patients with ulcerative colitis.
