Three Cases of Chylothorax After Lung Cancer Surgery: Possible Lymphatic Vessel Variation in the Upper Right Mediastinum.
Article in Clinical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Postoperative chylothorax is an uncommon complication after lung cancer resection. However, chylous leakage caused by iatrogenic injury of aberrant mediastinal lymphatic vessels often presents massive drainage and fails conservative treatment, requiring reoperation. A retrospective analysis was performed on three patients who underwent reoperation for refractory massive chylothorax after radical resection of right upper lobe lung cancer between October 2022 and November 2023 in our center. Intraoperatively, chylous fistulas were consistently detected at the junction of the upper margin of the azygos arch and the anterolateral trachea in the right superior mediastinum. An aberrant lymphatic tubular structure was directly visualized at this anatomical site during one primary operation. Preventive suturing may be considered at this anatomical junction during extensive right superior mediastinal lymphadenectomy to prevent postoperative chylothorax.
