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

Reactivation of latent VZV remains a significant cause of morbidity after SCT. Twenty-five percent or more of patients undergoing SCT will experience zoster within the first year after transplant. Short-course (<1 year) prophylaxis with acyclovir has been shown to be effective, but compliance with five times daily dosing may be problematic. We conducted a randomized, double-blind, placebo-controlled trial of valacyclovir (VACV) 1000 mg twice daily from 4 through 24 months after SCT for the prevention of VZV. Fifty-three VZV-seropositive transplant recipients (17 auto-SCT, 36 allo-SCT) were randomized at a median of 163 days after SCT. In a modified intent-to-treat analysis of 49 patients who took study drug, 0 of 22 in the VACV arm experienced zoster reactivation, compared with 6 of 26 (23%) in the placebo arm (P=0.025). Thirty-two subjects completed therapy through the second year post transplant or first episode of zoster. Adverse events resulting in discontinuation were more frequent in the placebo group (5 of 26 vs 3 of 27 for placebo and study drug, respectively). VACV at a dose of 1000 mg twice daily through 24 months after transplant is well tolerated and effective in suppressing shingles after SCT.
