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
objectiveChronic thromboembolic pulmonary hypertension (CTEPH) is a rare complication of acute pulmonary embolism, being characterized by persistent obstruction of pulmonary vessels and leading to increased pulmonary vascular resistance and right ventricular failure. Although pulmonary endarterectomy is the preferred treatment, medical therapies may offer clinical benefits in specific settings. We sought to evaluate the clinical and hemodynamic response of CTEPH patients treated with sildenafil and ambrisentan upfront combination therapy.
methodsThis was a retrospective cohort study including patients with operable and inoperable CTEPH. The patients were followed from 2019 to 2022 and were treated with sildenafil and ambrisentan as first-line therapy.
resultsFunctional and hemodynamic data were analyzed at baseline and after a minimum of six months of therapy. Following treatment, there was a notable improvement in functional class, natriuretic peptide levels, and invasive hemodynamics.
conclusionsThe combined use of sildenafil and ambrisentan appears to be associated with clinical, functional, and hemodynamic improvement in patients with CTEPH.
