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

This study investigates the impact of face shape on the pass rate of personal protective equipment N95 mask fit tests among Taiwanese healthcare workers (HCWs) during the COVID-19 pandemic. Fit tests are crucial for controlling and preventing infection, but research indicates that face shape can affect the test's effectiveness. HCWs underwent a qualitative fit test and were categorized into round, square, long, and oval face shapes based on their profile pictures. A total of 352 HCWs participated the intervention, and 287 participants passed the test, among those participants, long shaped face had a passing rate of 80.2% and oval-shaped faces was 91.7%, while round-shaped faces had the lowest passing rate of 42.9%. This study reveals that long and oval shaped face participants in Taiwanese healthcare workers have a higher fitting rate than round-shaped participants, indicating better mask fit test pass rates.
