Phenotyping persistent pulmonary hypertension of the newborn: recognition of its persistence across world symposium on pulmonary hypertension classifications.
Review in Journal of perinatology : official journal of the California Perinatal Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The earliest clinical sign of pulmonary vascular disease in neonates is persistent pulmonary hypertension of the newborn (PPHN), traditionally classified as World Symposium on Pulmonary Hypertension (WSPH) Group 1. Typical PPHN is defined by the delayed transition from intra- to extra- uterine life with failure of pulmonary artery pressures to fall after delivery. This results in sustained elevation of pulmonary vascular resistance and contributes to hypoxemic respiratory failure (HRF). However, early HRF can also arise from atypical PPHN phenotypes that may persist beyond the expected resolution of typical PPHN and are often classified within WSPH Groups 2, 3 and 5. In addition, a history of PPHN can be associated with the childhood and adulthood PH. In this perspective, we highlight the diverse etiologies contributing to the PPHN phenotype, with a focus on Group 3 disease, and propose a physiology-based framework to classify PPHN and delineate disease trajectories.
