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
Introduction: Pulmonary hypertension (PH) is characterized by increased pulmonary artery pressure (PAP) and pulmonary vascular resistance (PVR) due to loss of arterial elasticity and vascular obstruction. The dicrotic notch index (DNI) represents reflected wave characteristics and vascular elasticity, potentially serving as an important marker in PH assessment. Aim: This study evaluates the relationship between DNI and PVR, PAPs, and other hemodynamic and clinical parameters in PH patients. Material and methods: A retrospective analysis was conducted on 76 patients diagnosed with pulmonary arterial hypertension (PAH), chronic thromboembolic pulmonary hypertension (CTEPH), or normal PAPs who underwent right heart catheterization (RHC). PAP waveforms were analyzed to determine DNI. Correlations between DNI and hemodynamic, clinical, and echocardiographic parameters were assessed using Pearson's correlation coefficient. Logistic regression and ROC analysis were performed to evaluate the DNI's predictive value. Results: DNI showed significant positive correlations with systolic PAP (sPAP) ( Conclusions: DNI is correlated with key hemodynamic parameters such as PVR and mPAP, underscoring its potential as a crucial marker in the assessment of PAH and CTEPH patients. Additionally, DNI exhibited significant correlations with echocardiographic measurements and clinical indicators, suggesting its utility in evaluating pulmonary arterial stiffness and resistance. Further research is needed to validate these findings in larger cohorts and to establish standardized protocols for DNI measurement in clinical practice.
