Parenteral prostacyclin utilization in patients with pulmonary arterial hypertension in the intermediate-risk strata: a retrospective chart review and cross-sectional survey.
Article in BMC pulmonary medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundCurrent clinical guidelines support use of parenteral prostacyclin therapy for patients with pulmonary arterial hypertension (PAH) at intermediate risk. The objective of this study was to assess parenteral prostacyclin therapy use among patients at intermediate risk according to the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension (COMPERA) 2.0 four-strata risk assessment model.
methodsThis was a retrospective chart review and cross-sectional online survey of healthcare professionals (HCPs). Included patients were classified as intermediate-low or intermediate-high risk per COMPERA 2.0 between 2016 and 2020 (index visit), initiated on a parenteral prostacyclin any time following intermediate risk assessment, and had World Health Organization (WHO) Functional Class (FC), 6-minute walk distance (6MWD), and B-type natriuretic peptide/N-terminal pro B-type natriuretic peptide (BNP/NT-proBNP) assessments at index and first comprehensive follow-up visits (follow-up).
resultsA total of 139 HCPs (53% community-based, 47% Pulmonary Hypertension Care Center-based) participated in the survey and provided 350 patient records; among these, mean age (SD) was 54.1 (15.3) years and 52% were female. Median (IQR) time from parenteral prostacyclin initiation to follow-up was 3.0 months (2.0, 7.0). At parenteral prostacyclin initiation for the 280 patient records with available COMPERA 2.0 assessments, 62% of patients were intermediate-high risk, 33% were intermediate-low risk and 3% were low risk, improving to 38%, 53%, and 8%, respectively, at follow-up.
conclusionsImprovements were seen for the individual COMPERA 2.0 risk calculator parameters and for several other clinical parameters. Findings from this study substantiate recent guidelines suggesting earlier use of this treatment in intermediate-risk patients with PAH. CLINICAL TRIAL NUMBER: Not applicable.
