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
aimsNon-invasive myocardial work integrates myocardial deformation and afterload and may improve assessment of left ventricular (LV) function. We evaluated whether preoperative myocardial work indices predict postoperative outcomes in heart failure patients undergoing durable left ventricular assist device (LVAD) implantation.
methodsIn this retrospective cohort, transthoracic echocardiography (TTE) with simultaneous non-invasive blood pressure measurement was used to derive LV global work index (GWI). Clinical risk scores (HeartMate II risk score [HMRS], HeartMate 3 risk score [HM3RS], European System for Cardiac Operative Risk Evaluation II [EuroSCORE II], Michigan right-heart-failure score [MRHFS], and EUROMACS right-heart-failure score [EUROMACS-RHF]) were calculated. Univariable and multivariable predictors of postoperative right heart failure (RHF) and mortality were evaluated using ridge-penalized logistic regression with bootstrap validation and ROC analysis. Continuous predictors were standardized (per 1 standard deviation).
resultsFifty-three patients were included. In penalized regression, MRHFS was the strongest independent predictor of postoperative RHF (OR per 1-SD 2.80; 95% CI 1.55-5.05; p = 0.001; apparent AUC ≈ 0.90). Lower preoperative LV-GWI independently predicted long-term mortality (adjusted OR per 1 mmHg 0.98; 95% CI 0.97-0.99; p = 0.002) and showed high apparent discrimination (apparent AUC ≈ 0.90); optimism-corrected AUC for a multivariable model including standardized GWI, age, EuroSCORE II, and MRHFS was 0.88. Conventional TTE indices were not predictive after adjustment.
conclusionsIn patients undergoing durable left ventricular assist device implantation, preoperative non-invasive global left-ventricular myocardial work index improved prediction of mortality beyond established scores. The Michigan right-heart-failure score accurately identified patients at risk of right-ventricular failure.
