Evaluation of the aerosol generating potential of endoscopic dacryocystorhinostomy.
Article in Laryngoscope investigative otolaryngology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeThe COVID-19 pandemic gave rise to renewed concerns of the transmission risks posed by surgeries on sites of high viral colonization such as the nasopharynx. Endoscopic dacryocystorhinostomy (DCR) involves the creation of a new tear duct from the lacrimal sac to the nasal cavity. The purpose of this project is to determine if endoscopic DCR is an aerosol generating procedure (AGP).
methodsAn optical particle sizer (OPS) was used to intraoperatively quantify aerosol concentrations during four cases of endoscopic DCR. The OPS sampled the air once every 60 seconds throughout the operations. The time of important operative steps were documented and correlated with OPS readings. Particle concentrations during each major surgical step were compared to baseline readings by the Mann Whitney
resultsThere were statistically significant increases in median particle concentrations during laryngeal mask airway intubations for both particles 0.3 to 5.0 μm and >5.0 μm (
conclusionsEndoscopic DCR in itself does not appear to be an AGP. It is, however, associated with other aerosol generating events such as laryngeal mask intubation, and thus requires appropriate personal protective equipment. Cautious interpretation of the results is encouraged given the limitations of OPS. LEVEL OF EVIDENCE: 4.
