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 aimed to determine whether wearing N95 masks for 4 h significantly affected physiological indicators in obese operating room staff compared to surgical masks (SMs). In this randomized crossover trial, the physiological impacts of wearing SMs and N95 masks for 4 h was analysed among 20 obese operating room staff. The data were connected to a nasal sampling tube using the Capnostream 20p monitor. The primary outcome was the change in venous carbon dioxide partial pressure (PvCO
