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

Purpose: To evaluate the changes in intraocular pressure (IOP) and superficial retinal vessel density after short-term application of N95 respirators or regular surgical masks in healthy subjects. Methods: Twenty-seven healthy subjects were recruited, and each received three interventions: without wearing a mask, wearing a regular surgical mask, and wearing an N95 respirator for 30 min. With a one-hour washout interval between mask conditions. IOP and superficial retinal vessel density were measured immediately before and after each intervention. Results: There was no significant difference in IOP in either eye (analyzed on a per-eye basis, Conclusion: Short-term (30-min) application of an N95 respirator or surgical mask does not significantly affect IOP or superficial retinal vessel density in healthy young adults. These findings provide preliminary evidence regarding the ocular safety of short-term mask use in this population.
