Quantitative assessment of pulmonary blood flow redistribution in the classification of group 1 and group 4 pulmonary hypertension.
Article in Quantitative imaging in medicine and surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: All patients with pulmonary hypertension (PH), without left heart disease or lung diseases, need further distinguishing between pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). This study aimed to investigate the value of quantitative assessment of pulmonary blood flow redistribution in further classification. Methods: Forty-six patients who underwent echocardiography and computed tomography pulmonary angiography at The First Affiliated Hospital of Xi'an Jiaotong University were included in this cross-sectional study, and all patients were categorized into a non-PH group (18 cases), a PAH group (12 cases), and a CTEPH group (16 cases). The diameter of the left ventricle and right ventricle were measured. The volumes of the main, right, and left pulmonary arteries were calculated. The total blood volume (TBV), the blood volume of vessels at the cross-section with an area <5 mm Results: The diameter of the right ventricular, and the volumes of the main pulmonary artery, right pulmonary artery, and left pulmonary artery were not significantly different between the PAH and CTEPH group (P>0.05). The BV10 of CTEPH were significantly lower than those of the PAH group for the whole lung (32.69‰±13.53‰ Conclusions: Pulmonary vessel volume increased in PAH, particularly in larger-caliber vessels and the pulmonary artery, while it decreased in CTEPH, especially in larger-caliber vessels and the RLL.
