Chronic Thromboembolic Pulmonary Disease: Right Ventricular Function and Pulmonary Hemodynamics in a 4-Year Follow-Up.

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
Chronic thromboembolic pulmonary disease (CTEPD) with or without pulmonary hypertension (PH) is characterized by persistent perfusion defects and progressive pulmonary vascular dysfunction after acute pulmonary embolism (PE), despite adequate anticoagulant therapy. We aimed at assessing clinical, hemodynamic, and functional evolution in patients screened for CTEPD with persistent lung perfusion scintigraphy (Q-scan) defects to identify non-invasive predictors of right ventricular (RV) impairment and development of exercise-induced pulmonary hypertension (ExPH). We analyzed 55 patients with a history of PE and no prior cardiopulmonary disease, stratified by perfusion (Q)-scan at 4 months into Q-scan-positive (n = 35) and Q-scan-negative (n = 20). At that time, all patients underwent echocardiography, cardiopulmonary exercise testing (CPET), and exercise stress echocardiography (ESE). Clinical evaluation and resting echocardiography were repeated at 24, 36, and 48 months. At baseline, Q-positive patients had higher NT-proBNP levels and greater PESI scores. At 4 months, they exhibited a higher prevalence of exercise-induced pulmonary hypertension (ExPH) on both CPET and ESE (
