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
purposeRecently, the severe acute respiratory syndrome coronavirus disease-2019 (COVID-19) has shown great health issues globally. The COVID-19 disease has caused economic issues, health issues and a greater number of deaths. However, many advanced techniques have been developed to segment the pulmonary lobe of COVID-19, but that techniques were inadequate for pulmonary lobe segmentation. The traditional models are not capable of capturing subtle changes in lung tissue and complex lung structure that are caused by COVID-19. Therefore, to improve the pulmonary lobe segmentation of COVID-19 using Computed Tomography (CT) image, an effective method, namely O-Segnet-Fusion-Unext (Osegnet-F-Unext), is proposed.
methodAt first, the input COVID-19 CT image is fed to the image enhancement process. The image enhancement is performed by the power-law transformation technique. Finally, an enhanced image result is given to the pulmonary lobe segmentation. Therefore, the lobe segmentation is carried out with the proposed Osegnet-F-Unext, where the developed model is the combination of O-Segnet and Unext networks. Additionally, the evaluation of the performance of the Osegnet-F-Unext model is done by using segmentation accuracy, Jaccard coefficient and dice coefficient.
resultsExperimental output shows that the O-Segnet F-Unext method obtained the highest segmentation accuracy as 91.55%, Jaccard coefficient as 0.903 and dice coefficient as 0.898.
conclusionThe proposed Osegnet-F-Unext model provides a reliable and effective method for the pulmonary lobe segmentation of COVID-19.
