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
introductionPatients with ovarian cancer often present with massive ascites, leading to significant protein loss during surgical procedures. Although cell-free concentrated ascites reinfusion therapy (CART) is used in palliative settings to mitigate protein loss, its application in intraoperative settings remains unexplored.
methodsWe retrospectively evaluated patients who underwent intraoperative CART for ovarian cancer treatment between March 2022 and 2025, compared two ascitic fluid collection methods (syringe and roller pumping), and analyzed operative parameter, fluid collection efficiency, albumin recovery, and adverse event-related data.
resultsAmong the 12 patients included in this study, seven (58.3%) underwent CART using the roller pumping method, which significantly reduced the collection time compared with the syringe method (9 vs. 22 min, p < 0.05). The median collection speed was also significantly higher with the roller pumping method (404 vs. 140 mL/min, p < 0.05). Approximately 70% of the albumin in the collected ascitic fluid was successfully reinfused. Adverse events included transient hypotension (16.7%) and hypertension (25.0%), both of which resolved without intervention.
conclusionIntraoperative CART is a feasible and safe technique for protein loss management in patients undergoing surgery for ovarian cancer. The roller pumping method significantly shortened ascites collection time and reduced surgical burden.
