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 thoracic duct uses the pulsation of accompanying arteries to facilitate lymphatic flow. However, the lymphatic flow mechanism cannot be explained when it does not accompany the arteries. This study aimed to clarify the anatomical position of the thoracic duct and surrounding structures and determine the differences in the thoracic duct length and course during inspiration and expiration.
methodsSix cadavers were dissected to observe the positional relationship between the thoracic duct and surrounding structures. Image sequences of anatomical sections from the Visible Korean Human Open Resource were observed and reconstructed to understand their three-dimensional positioning. Inspiratory and expiratory computed tomography scans were used to measure and examine respiratory variations in the distance between the arterial landmarks to predict the thoracic duct length.
resultsThe thoracic duct accompanied the arteries for most of its course and was sandwiched between the arteries and pleura, entering the mediastinum. However, there was an area on the cranial side of the aortic arch where the thoracic duct did not accompany the arteries. The distance between the arterial landmarks in this area, which approximate the thoracic duct length, was significantly longer during inspiration (39.3 ± 7.81 mm) than during expiration (31.49 ± 7.01 mm).
conclusionThis study suggests that the pleura entering the mediastinum pushes the thoracic duct toward the arteries to promote lymphatic flow generation by arterial pulsation. Additionally, this study suggests that the lymphatic flow in the thoracic duct is generated by the expansion and contraction of the thoracic duct with respiratory movement.
