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

Bell's palsy is an idiopathic, acute, unilateral peripheral facial nerve paralysis, where incomplete or failed recovery causes substantial social and psychological stress to the patient, seriously influencing their quality of life and social activities. We conducted a bibliometric investigation of the knowledge structure and frontier hotspots in Bell's palsy research. Bell's palsy publications between 2002 and 2021 were retrieved from Web of Science. CiteSpace, VOSviewer, and an online bibliometric platform were used for visual, burst, citation, and co-occurrence analyses, respectively. A total of 1,378 publications were included. The annual Bell's palsy publication output followed an upward trend from 2002 to 2021. The USA and Harvard University published the most Bell's palsy research articles. Yeo SG and
