The Pulmonary Hypertension Global Patient Survey: Understanding the Invisible Burden of Paediatric Pulmonary Hypertension.
Article in Pulmonary circulation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 Pulmonary Hypertension Global Patient Survey (PH GPS) provides the first international examination of experiences among children with pulmonary hypertension (PH) and their caregivers. Through an online survey distributed via PH associations across 32 countries, we collected responses from 136 caregivers about diagnostic journeys, treatment experiences, healthcare access and research participation. Qualitative analysis revealed challenges around the 'invisible' nature of PH, with caregivers describing how schools and communities sometimes doubted their child's limitations in the absence of visible symptoms, adding to family burden. Quantitative findings demonstrated extensive caregiver burden with 40% providing constant care while facing significant employment consequences, including leaving work altogether, reduced hours, or career changes. Although 78.8% of children accessed specialist centres, significant barriers persisted: 41.2% encountered diagnostic delays exceeding 6 months, 34.8% travelled over 2 h for appointments and 27.7% received no healthcare cost reimbursement. Treatment experiences revealed 37.7% of children experienced side effects, yet only one-third discussed changes with their clinical teams, reflecting pragmatic decisions within limited therapeutic options. Research participation was low (19.2%), though families with trial experience showed greater willingness for future participation, compared to those without experience (70.8% vs. 49.5%). Barriers centred on awareness gaps (16.4%), safety concerns (14.5%), and age-related considerations (10.9%), distinct from adult PH populations where logistical challenges predominate. These findings demonstrate that paediatric care must extend beyond medical management to address family needs including social-work assistance for benefits navigation, flexible care delivery models incorporating telemedicine, pro-active communication about treatment tolerability and research protocols designed with families from inception.
