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

Purpose: To evaluate the diagnostic performance of endogenous T1ρ mapping, compared with native T1 and T2 mapping, for identifying late gadolinium enhancement (LGE)-defined peri-infarct zones in acute ST-elevation myocardial infarction (STEMI) and chronic myocardial infarction (MI). Methods: This retrospective study included 35 patients with acute STEMI, 21 with chronic MI, and 35 healthy controls who underwent cardiac MRI with T1ρ, native T1, and T2 mapping between March 2022 and August 2025. LGE was used to delineate peri-infarct zones in patients with MI. A linear mixed-effects model accounting for within-participant clustering compared T1ρ values across myocardial segments. Receiver operating characteristic analysis was used to assess diagnostic performance. Results: Among the 56 patients with MI (mean age, 57 ± 13 years; 49 men), global T1ρ values were elevated in both acute STEMI and chronic MI compared with controls (both Conclusion: Endogenous T1ρ mapping may provide a contrast-free biomarker for myocardial tissue characterization in MI, with diagnostic performance comparable to T2 in acute STEMI and superior to native T1 and T2 in chronic MI.
