Prognostic value of selected echocardiographic, impedance cardiographic, and hemodynamic parameters determined during right heart catheterization in patients qualified for heart 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
The aim of the study was to verify prognostic value of selected echocardiographic (UKG), impedance cardiography (ICG), and right heart catheterization (RHC) parameters in systolic heart failure (HF). UKG, ICG, and RHC were performed in 46 patients with chronic HF with ejection fraction <35%. During a 1-year follow-up, composite endpoint (death or hospitalization due to HF exacerbation) was achieved by 23 (50.0%) patients. Analysis of receiver operating characteristic (ROC) curves identified UKG parameters: inferior vena cava diameter on inspiration (IVCinsp) >13 mm [area under curve (AUC), 0.791], right atrial (RA) >5.2 cm (AUC 0.710) and ventricular dimension (RVD) >3.5 cm (AUC 0.717), tricuspid annular plane systolic excursion (TAPSE) <17 mm (AUC 0.682), and its velocity (S'RV) <6.07 cm/s (AUC 0.716) as unfavorable prognostic factors. RHC parameters: low values of cardiac index (CI < 2.1 L/min; AUC 0.846) and high pulmonary capillary wedge pressure (PCWP > 24 mmHg; AUC 0.773) turned out to be the most accurate single predictors of worse outcome. Prognostic value of non-invasive parameters was improved due to the use of their composite measures: IVC% × TAPSE (<430%/mm; AUC 0.826), RVSP/TAPSE (>2.4 mmHg/mm; AUC 0.800), IVC% × SBP (>2097% mmHg; AUC 0.826), and RA × IVCinsp/S'RV (>11.8 cm s; AUC 0.839). In conclusion, composite measures based on non-invasive parameters, such as IVC%/TAPSE, RVSP/TAPSE and RA × IVCinsp/S'RV, may provide equally accurate prognosis as the invasive examination. PCWP and CI determined during RHC were the best individual predictors of the composite endpoint. In addition, echocardiographic parameters: RVD, RA, IVC, TAPSE, and S'RV are accurate predictors of the unfavorable outcome.
