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

Background: Amenamevir is a helicase-primase inhibitor with novel mechanisms of antiherpetic action. A patient-initiated single-dose regimen showed clinical efficacy for genital herpes in a phase 2 study. Methods: In this phase 3 study, adult immunocompetent patients with recurrent genital herpes and able to accurately recognize prodromal symptoms were randomly assigned to administer amenamevir 1200 mg or placebo as a patient-initiated therapy within 6 hours after onset of prodromal symptoms. The primary efficacy endpoint was time to healing of all genital herpes lesions. Results: In the modified intention-to-treat population, which excluded patients with aborted lesions (amenamevir, n = 89; placebo, n = 97), the median time to all lesion healing was 4.0 days for amenamevir versus 5.1 days for placebo (hazard ratio, 1.60 [95% confidence interval, 1.19-2.15]; Conclusions: Patient-initiated single-dose amenamevir reduced the time to all lesion healing of recurrent genital herpes versus placebo, with no safety concerns, suggesting it could be an effective treatment option for patients with recurrent genital herpes.
