Cardiac myosin-binding protein C: potential early biomarker of myocardial injury in coronary artery bypass surgery.

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
backgroundIn this study, it was aimed to evaluate the diagnostic value of myosin binding protein C (cMyBP-C) as a new cardiac injury marker in demonstrating myocardial injury in Coronary Artery Bypass Surgery patients.
methodsProspectively collected data from 60 coronary artery bypass surgery patients were evaluated and the results were compared. The study included 60 patients who applied to the Cardiovascular Surgery Clinic between March 2024 and September 2024 and who were going to undergo coronary bypass surgery. The patients' high-sensitivity cardiac troponin T (hs-cTnT) and Cardiac myosin binding protein C (cMyBP-C) levels, clinical and descriptive information were analyzed before the bypass procedure, after the cross clamp and at the sixth hour post-operation.
resultsArea under curve (AUC) for cMyBP-C for Length of ICU stay was 0.673, whereas AUC mean for hs-cTnT was 0.590. For cMyBP-C preop cut off level at 4836.50, sensitivity was 66.7% and specificity was 22.2%. Preoperative cMyBP C was significantly correlated with HT(r=-0,299; p < 0.05), DM (r=-0.350; p < 0.01), cardiopulmonary bypass time (CPB) time (r=-0.339; p < 0.01), and preop lactate (0.349; p < 0.01). Postoperative cMyBP-C level was significantly correlated with HT(r=-0.320; p < 0.05), DM (r=-0.462; p < 0.01), Perioperative lactate (r = 0.277; p < 0.05) and lactate at 6th hour (r = 0.280; p < 0.05). DM (B = 2602.92; p < 0.01), Length of hospital stay (B = 254.83; p < 0.05) and ascending aorta with (B = 249.50; p < 0.05) positively association with perioperative cMyBP-C levels.
conclusionThe cMyBP-C biomarker may be an alternative biomarker for myocardial injury in cases where high hs-cTnT levels are insufficient to indicate myocardial injury. DM should be considered as an important and determining variable in myocardial injury, including hs-cTnT.
