1 · What the graph read from it

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.

2 · The registry

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

backgroundThe clinical and economic burden of pulmonary arterial hypertension (PAH) is poorly understood outside the United States. This retrospective database study describes the characteristics of patients with PAH in England, including their healthcare resource utilisation (HCRU) and associated costs.

methodsData from 1 April 2012 to 31 March 2018 were obtained from the National Health Service (NHS) Digital Hospital Episode Statistics database, which provides full coverage of patient events occurring in NHS England hospitals. An adult patient cohort was defined using an algorithm incorporating pulmonary hypertension (PH) diagnosis codes, PAH-associated procedures, PH specialist centre visits and PAH-specific medications. HCRU included inpatient admissions, outpatient visits and Accident and Emergency (A&E) attendances. Associated costs, calculated using national tariffs inflation-adjusted to 2017, did not include PAH-specific drugs on the High Cost Drugs list.

resultsThe analysis cohort included 2527 patients (68.4% female; 63.6% aged ⩾50 years). Mean annual HCRU rates ranged from 2.9 to 3.2 for admissions (21-25% of patients had ⩾5 admissions), 9.4-10.3 for outpatient visits and 0.8-0.9 for A&E attendances. Costs from 2013 to 2017 totalled £43.2M (£33.9M admissions, £8.3M outpatient visits and £0.9M A&E attendances). From 2013 to 2017, mean cost per patient decreased 13% (from £4400 to £3833) for admissions and 13% (from £1031 to £896) for outpatient visits, but increased 52% (from £81 to £123) for A&E attendances.

conclusionPAH incurs a heavy economic burden on a per-patient basis, highlighting the need for improved treatment strategies able to reduce disease progression and hospitalisations.
