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
backgroundWhole blood viscoelastic tests (VETs) are key for detecting fibrinolysis during orthotopic liver transplantation (OLT). The Quantra System introduces a novel parameter, clot stability to lysis (CSL), for quantifying fibrinolysis. The objective was to assess CSL performance relative to established VET measures.
methodsData were drawn from a multicenter, prospective study of adults undergoing OLT, with Quantra and ROTEM delta testing performed in parallel. This sub-analysis focused on fibrinolysis-positive samples, emphasizing discordant findings between platforms.
resultsAmong 125 enrolled patients, 13 intraoperative samples involving the use of heparin showed discordant results. Calibrated automated thrombinography revealed that Quantra reagents produce slower, reduced thrombin generation compared to ROTEM, diminishing thrombin activatable fibrinolysis inhibitor (TAFI) activity. This enhances sensitivity of Quantra to detect fibrinolysis in these samples.
conclusionsQuantra's CSL parameter demonstrated improved detection of fibrinolysis in heparinized samples and may support individualized fibrinolysis management during OLT. Broader clinical validation is warranted.
