The Possible Factors Correlated with The Higher Risk of Getting Infected by COVID-19 in Emergency Medical Technicians; A Case-Control Study.
Article in Bulletin of emergency and trauma, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
objectiveTo assess the possible factors associated with increasing risk of COVID-19 among EMTs.
methodsThis study was a case-control study conducted in Tehran, Iran. Case group was consisted of confirmed COVID-19 EMTs based on the results of reverse transcriptase polymerase chain reaction and/or lung computed tomography scan. Healthy EMTs were randomly selected as control group. Patients were asked to fill out a checklist including demographic data, data related to the work situation (such as number of missions and type of mask and cloth) and PPE precautions.
resultsSixty-eight patients and 148 healthy persons took part in this study as case and control group, respectively. Having two EMTs involved directly in taking care of patients (
conclusionWe found that the type and method of use of PPE were correlated with the increasing risk of COVID-19 in EMTs. Also, we found that when two EMTs were involved directly in taking care of the patients, and those who worked with a confirmed case teammate, more frequently affected.
