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

<p>Introduction: Pulmonary vascular abnormalities coexist with interstitial lung disease (ILD), leading to a spectrum of physiologic impairments. We hypothesized that ILD patients with exercise intolerance have a heterogenous hemodynamic profile when assessed by invasive cardiopulmonary exercise testing (iCPET).

methodsFrom January 2018 to December 2023, we prospectively performed iCPET for several conditions. The primary outcome of the study was to assess the hemodynamic phenotypes both at rest and during exercise of ILD patients with exercise intolerance, which cannot be fully explained by the severity of ILD.

resultsOf the 43 ILD patients included in the study, 10 (23%) had no pulmonary hypertension (PH), 16 (37%) had no PH with pulmonary vascular resistance (PVR) >2 WU, 7 (16%) had precapillary PH, 7 (16%) had postcapillary or combined pre- and postcapillary PH, and 3 (7%) had unclassified PH. Four (9%) patients had exercise PH. Forced vital capacity, diffusion capacity for carbon monoxide, peak oxygen consumption, and resting partial pressure of oxygen (PaO

conclusionPatients with ILD and exercise intolerance have several hemodynamic phenotypes with parameters that reveal worse exercise performance from no PH to no PH with elevated PVR to precapillary PH. </p>.
