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

backgroundExercise pulmonary hypertension (PH) was defined by a mean pulmonary arterial pressure (mPAP)/cardiac output (CO) slope >3 mmHg·min·L PATIENTS AND

methodsThe PEX-NET (Pulmonary Haemodynamics during Exercise Network) registry enrolled patients who underwent clinically indicated right heart catheterisations both at rest and ergometer exercise from 23 PH centres worldwide. In this retrospective analysis we included subjects with resting mPAP <25 mmHg and complete haemodynamic data at rest and exercise in the same body position. Mixed effects Cox proportional hazard models with random effect centre were applied to identify independent markers of prognosis among the haemodynamic parameters.

resultsWe included 764 patients (64% females; median (interquartile range) age 59 (46-69) years and mPAP 17 (14-20) mmHg). Median (range) observation time was 6.8 (0.1-15.9) years and 87 patients (11%) died during follow-up. After adjustment for age, sex, haemoglobin level and resting haemodynamics, CO (hazard ratio (HR) 0.85, 95% CI 0.77-0.93; p=0.001) and transpulmonary gradient (HR 1.04, 95% CI 1.00-1.08; p=0.044) at peak exercise and the mPAP/CO slope (HR 1.12, 95% CI 1.06-1.18; p<0.001) were the only independent predictors of prognosis. Patients with a mPAP/CO slope >3 mmHg·min·L

conclusionThe mPAP/CO slope is a robust and independent predictor of prognosis in patients with normal or mildly elevated resting PAP that provides prognostic information beyond resting haemodynamics and appears suitable to define exercise PH.
