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 elimination of cyclosporin A was assessed in eight pediatric renal transplant patients who received calcium channel blockers concomitantly with their immunosuppressive therapy. In three children, verapamil decreased the rate of elimination of cyclosporin A. In five children who received nifedipine, cyclosporin A elimination was also impaired, which contrasts with the reports in adult patients indicating that this calcium channel blocker has no effect on cyclosporin A elimination. When both calcium channel blockers were used on separate occasions in the same patient, nifedipine was less potent than verapamil in depressing cyclosporin A elimination. Although the number of subjects studied is small, these results likely indicate that nifedipine, as well as other calcium channel blocking drugs, must be used with caution in pediatric renal transplant patients.
