Beyond the shunt: Divergent insights from hyperoxia testing and contrast echocardiography in adults with pulmonary hypertension.

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
Our objective was to evaluate the agreement between hyperoxia test (HT) and contrast transthoracic echocardiography (CE) for shunt detection in patients with pulmonary hypertension (PH) and unexplained hypoxemia. We retrospectively collected data from consecutive hypoxemic PH patients over a 2-year period. The tests were conducted sequentially, and their agreement was assessed using Cohen's kappa coefficient. Fifty-five PH patients were included, with a median age of 67 years [58-73]; among them, 35 (63.6%) were classified as having pulmonary arterial hypertension (PAH). The mean pulmonary arterial pressure was 39 mmHg [34-49] and pulmonary vascular resistance (PVR) was 5.3 WU [3.8-8.9]. P
