Consequences of FFP3 mask usage on venous blood gases.
Article in Irish journal of medical science, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
objectives/hypothesisTo investigate the effect of FFP3 mask usage on venous blood gases (VBG) and some subjective symptoms
methodsVBG analyses and subjective symptom questionary were obtained from 15 healthcare proffesionals before and after 4-h FFP3 mask usage.
resultsWearing an FFP3 mask for 4 hours did not change any venous blood gas parameters between pre- and post-values, statistically. According to an 8-symptom questionary, only nausea did not show any significance. Headache, lightheadedness, visual difficulties, shortness of breath, palpitation, confusion, and difficult communication showed statistically significant difference between pre and post values.
conclusionFour-hour use of FFP3 mask did not cause any significant VBG change. Although the participants complained about some subjective symptoms, this study indicated that long-term use of FFP3 mask did not cause any significant discomforts, and it was well tolerated.
