Diagnostic accuracy and cost-effectiveness of the CAR-OLT score in predicting cardiac risk for liver transplantation.

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
backgroundThe CAR-OLT score predicts major adverse cardiovascular events 1 year after liver transplant (LT).
aimTo test the hypothesis that the CAR-OLT score may help avoid cardiac stress tests in LT candidates.
methodsThis retrospective single-center cohort study included all adult patients undergoing elective evaluation for first cadaveric donor orthotopic LT for liver cirrhosis with or without hepatocellular carcinoma at Fondazione Policlinico Universitario Agostino Gemelli Istituto di Ricerca e Cura a Carattere Scientifico in Rome, Italy. Cardiac contraindications for LT listing were defined after a center-specific cardiac workup, which included cardiac stress tests for most patients. The diagnostic accuracy of the CAR-OLT score was evaluated using the area under the receiver operating characteristic (AUROC) method.
resultsA total of 342 LT candidates were evaluated between 2015 and 2019, with a moderate cardiovascular risk profile (37% diabetes, 34% hypertension, 22% obesity). Of these, 80 (23%) candidates underwent coronary angiography. Twenty-one (6%) candidates were given cardiac contraindications to LT listing, 48% of which were due to coronary artery disease. The CAR-OLT score predicted cardiac contraindications to LT listing with an AUROC of 0.81. The optimal cut-off for sensitivity was a CAR-OLT score ≤ 23, which showed a 99% negative predictive value for cardiac contraindications to LT listing. A total of 84 (25%) LT candidates with a CAR-OLT score ≤ 23 underwent 87 non-invasive cardiac tests and 13 coronary angiographies pre-listing, with estimated costs of approximately 48000€. The estimated savings per patient was €574.70 for the Italian National Health System.
conclusionA CAR-OLT score ≤ 23 can identify LT candidates who can be safely listed without the need for cardiac stress tests, providing time and cost savings. These findings require external validation.
