Clinical significance of postoperative cardiothoracic ratio for postoperative pleural effusion following hepatectomy.
Article in BMC surgery, 2025. 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
backgroundAlthough several preoperative risk factors for postoperative pleural effusion (POPE) after hepatectomy have been reported, few postoperative predictors have been investigated. We aimed to examine risk factors for clinically relevant POPE (CR-POPE) and whether cardiothoracic ratio (CTR) could be a predictive factor.
methodsParticipants in this retrospective investigation comprised 382 patients who underwent hepatectomy between January 2012 and December 2021. Perioperative characteristics that were considered potential risk factors for CR-POPE were evaluated. CR-POPE was defined as having undergone thoracentesis or thoracic drain placement.
resultsPatients were divided into a CR-POPE group (n = 38; 10.0%) and a non-CR-POPE group (n = 344; 90.0%). The CR-POPE group showed significantly higher intraoperative infusion volume (P < 0.001) and lower intraoperative urine volume (P = 0.015). In multivariate analysis, abdominal incision with a reversed L-shape or inverted T-shape (odds ratio [OR] = 2.82.07, P = 0.038], diaphragm incision (OR = 9.05, P < 0.001), major postoperative complications excluding CR-POPE (OR = 7.70, P < 0.001), intraoperative infusion volume per body weight > 80 mL/kg (OR = 5.65, P < 0.001) and CTR on postoperative day (POD)1 > 59.0% (OR = 4.34, P < 0.001) were all independently associated with occurrence of POPE.
conclusionWe clarified risk factors for CR-POPE following hepatectomy. The occurrence of CR-POPE might be predictable from the CTR on POD1.
