Optical Analysis of Nasal Endoscopic Images From a Patient With Severe Acute Respiratory Syndrome Coronavirus 2.

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
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread worldwide; a simple diagnostic test is becoming increasingly important. Polymerase chain reaction tests of nasal swab samples are expensive and time-consuming. Detailed observation of the nasal cavity is required. No nasal endoscopic study regarding patients with SARS-CoV-2 has been published. Here, we compared endoscopic images of normal subjects and patients with allergic rhinitis (AR) to images from a patient with confirmed SARS-CoV-2 infection. Nasal cavity endoscopic images (of the inferior turbinate) were compared using the hue, saturation, and luminance (HSL) color system of Matrox Design Assistant, version 5.0. The multiple allergen simultaneous test was used to distinguish normal subjects from patients with AR. HSL patterns were compared among images. We enrolled 14 normal subjects and patients with AR and 1 patient with confirmed SARS-CoV-2 infection. The inferior turbinates of normal subjects and patients with AR were smooth and uniform, while those of the patient with SARS-CoV-2 were scratched and stretched. Although additional data are needed, optical analysis of nasal endoscopy images may be useful to screen for SARS-CoV-2 infection. This imaging method is rapid, non-invasive, and inexpensive.
