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
backgroundLoad dependence on left ventricular (LV) strain is under constant debate with its interference with prognostic implications remaining unclear. Consequently, we sought to investigate their interaction and prognostic value following acute myocardial infarction (AMI) using state-of-the-art cardiac magnetic resonance (CMR) imaging.
methodsIn total, 1235 patients (n = 795 ST-elevation [STEMI] and 440 non-STEMI) underwent CMR in median 3 days following AMI. Infarct characteristics were described by CMR using tissue characterisation (infarct size, microvascular obstruction, area at risk) and deformation imaging including LV global longitudinal and circumferential strain (GLS/GCS). Non-invasive haemodynamic indices included effective arterial elastance Ea (end-systolic pressure (ESP)/stroke volume) and the non-geometric LV end-systolic afterload index NGI [(ESP × LV end-systolic volume (ESV))/LV mass] for estimation of LV afterload. LV contractility was assessed using end-systolic elastance Ees (ESP/LV ESV). Ventriculo-arterial coupling was described as Ea/Ees. Major adverse cardiac events (MACE) were recorded within the first year.
resultsAll haemodynamic indices were impaired in patients with MACE during follow-up compared to patients without (p < 0.001-0.005). Ventriculo-arterial coupling showed the highest correlation to infarct properties (infarct size r = 0.51, p < 0.001) and deformation imaging (GLS r = 0.54, GCS r = 0.72, p < 0.001). GLS and GCS were associated with MACE independently of all haemodynamic indices (p < 0.001 for all except of GCS-Ea/Ees p = 0.024).
conclusionsNon-invasive haemodynamic indices are associated with outcome following AMI with ventriculo-arterial coupling showing the most prominent association to infarct properties and outcome. GCS showed higher correlation to haemodynamic indices compared to GLS whilst both are independent predictors for MACE.
