Cylindrical Tube Stethoscopes: The Value of Practical Equipment in the Management of Patients with Infectious Diseases.
Article in Infection and drug resistance, 2022. 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
Background: The COVID-19 pandemic has continued for more than two years since its outbreak. Due to the clinical auscultation needs of doctors when wearing airtight protective clothing, a cylindrical tube stethoscope was proposed to address this problem. However, the idea has been questioned by some experts. Methods: To address these questions, we performed three-part experiments using cylindrical tube stethoscopes. First, we performed laboratory tests to detect the sound intensity from a cylindrical tube stethoscope. Second, we improved the cylindrical tube stethoscope to achieve better results. Third, we revealed the difference in the auscultation effects of the cylindrical tube stethoscope and a conventional professional 3 M stethoscope. Results: From these experiments, we found that a narrow cylindrical tube with a diameter of 4.2 cm and a length of 20 cm equipped with a silicone gasket better auscultation of heart sounds. A cylindrical tube stethoscope and a 3 M stethoscope were used to perform stethoscope tests on 10 volunteers. The alveolar lung sounds were 44.478 decibels vs 49.529 decibels, the heart sounds were 46.631 decibels vs 41.109 decibels, and the intestinal sounds were 40.132 decibels vs 43.787 decibels, respectively. Conclusion: This improved cylindrical tube stethoscope can meet the auscultation requirements for cardiorespiratory and abdominal diagnosis during infectious disease pandemics.
