Association of pulmonary hypertension-targeted therapy and survival in precapillary pulmonary hypertension with mean pulmonary arterial pressure between 21 and 24 mmHg.
Article in ERJ open research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Introduction: The definition of pulmonary hypertension (PH) was recently changed and led to a new subset of PH patients with mildly impaired pulmonary haemodynamics, characterised by a mean pulmonary artery pressure (mPAP) of 21-24 mmHg and with a pulmonary vascular resistance (PVR) >2 WU. We evaluated the association of PH-targeted therapy and outcome in mild precapillary PH using the PVRI GoDeep meta-registry. Methods: All patients with mild precapillary PH (mPAP 21-24 mmHg, pulmonary arterial wedge pressure ≤15 mmHg and PVR >2 WU) diagnosed with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH) were enrolled. Patients were considered as "treated" if PH-targeted therapy was initiated within 6 months of diagnostic right heart catheterisation. Various statistical models, including in-depth sensitivity analyses, were used to examine the association between PH-targeted therapy and transplant-free survival. Results: 132 patients with group 1 or group 4 mild PH were identified, of whom 34 patients received PH-targeted therapy. There were no differences in baseline haemodynamics between untreated and treated groups, whereas treated patients suffered more frequently from renal comorbidities and required long-term oxygen treatment more often. Most prescribed were phosphodiesterase-5-inhibitors. PH-targeted therapy was associated with significantly higher survival rates. Cox-regression analyses revealed significantly reduced hazard ratios among treated patients adjusted for various confounders. Subgroup analyses in PAH (n=78) similarly indicated higher survival rates and reduced hazard ratios in treated patients. Conclusion: PH-targeted therapy may be associated with improved survival in PAH and CTEPH patients with mild PH. To mitigate potential bias of the results due to the retrospective study design, randomised controlled trials are warranted.
