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

backgroundMethamphetamine is increasingly recognized as a cause of pulmonary arterial hypertension (PAH). This study examines whether non-invasively measured metrics of right heart function, right atrial (RA) and right ventricular (RV) strain, are more impaired in methamphetamine-associated PAH (MA-PAH) compared with idiopathic PAH (IPAH).

methodsA retrospective cohort analysis of 51 patients with MA-PAH matched for mean pulmonary artery pressure (mPAP) with 51 patients with IPAH followed at the pulmonary hypertension clinic at the University of Utah was performed. Invasive hemodynamics and echocardiographic measures of right heart function, including RA strain and RV free wall strain, were compared.

resultsCompared to the matched IPAH group, MA-PAH patients had lower cardiac index (2.04 ± 0.84 vs. 2.52 ± 1.07 L/min/m DISCUSSION: Despite a similar mPAP, patients with MA-PAH had more RA dilation, RV dilation, lower RV systolic/diastolic function, and worse RA and RV mechanics as assessed by strain compared to patients with I-PAH. Our findings suggest that, in addition to causing remodeling of the pulmonary vasculature, methamphetamine may have a direct cardiotoxic effect on the right heart.
