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
backgroundChylothorax is a rare but potentially life-threatening complication after esophageal cancer resection. This study aims to investigate the impact of a strategy combining preoperative three-dimensional (3D) reconstruction of contrast-enhanced chest CT with olive oil ingestion on the incidence of chylothorax following esophageal cancer resection.
methodsWe retrospectively analyzed the clinical data of 357 patients who underwent esophageal cancer resection in the Department of Thoracic Surgery at Gansu Provincial People's Hospital from January 2019 to June 2024. Among them, 179 patients who underwent preoperative 3D reconstruction of contrast-enhanced chest CT combined with oral olive oil administration were assigned to the 3D reconstruction group, while 158 patients who did not receive these interventions served as the control group. The primary outcome measures included the incidence of chylous leakage and related perioperative outcomes.
resultsAll patients in both groups underwent surgeries successfully without any perioperative deaths. Compared to the control group, the 3D reconstruction group exhibited a significant decrease in the incidence of postoperative chylothorax (0% versus 8.2%, P < 0.001). The visualization rate of the thoracic duct during surgery was higher in the 3D reconstruction group compared to the control group (93.85% vs. 48.73%). Furthermore, patients in the 3D reconstruction group had less intraoperative bleeding (P = 0.003), shorter postoperative hospital stays (P = 0.003), and reduced chest drainage in the first three postoperative days (P < 0.001).
conclusionThis study reveals that preoperative three-dimensional reconstruction of chest using enhanced CT allows for the anticipation of thoracic duct anatomy. Additionally, the combination of preoperative oral olive oil administration significantly enhances the intraoperative visualization of the thoracic duct. This integrated strategy effectively reduces the incidence of postoperative chylothorax, demonstrating promising clinical application prospects.
