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

Introduction: This study aimed to investigate the clinical features and vaccine effectiveness of patients with the SARS-CoV-2 wild-type strain and the Delta variant. Methods: We retrospectively evaluated patients with the SARS-CoV-2 wild-type strain and the Delta variant. Results: The Delta-variant group showed a higher infection rate in minors, who had higher incidence of anosmia or dysgeusia and shorter incubation period. Unvaccinated patients had a 15.59-fold higher risk of severe classification than vaccinated patients. The viral clearance time was significantly shorter in the Delta-variant group. Conclusions: The Delta-variant group show higher transmissibility, and vaccination reduces the incidence of severe classification and promotes viral clearance.
