Prognostic value of transient ischemic dilation on Rubidium-82 positron emission tomography myocardial perfusion imaging.
Article in Journal of nuclear cardiology : official publication of the American Society of Nuclear Cardiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundTransient ischemic dilation (TID) of the left ventricular (LV) cavity is considered a high-risk marker in patients with abnormal single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI). Stress image acquisition with rubidium-82 (
methodsA total of 9878 consecutive patients with LVEF ≥40% undergoing rest/pharmacologic stress
resultsThe mean age of the cohort was 69.0 (11.7) years with 56.1% being female, 49.8% having known CAD, and 27.9% having abnormal perfusion (SSS>0). There were 451 cardiac deaths. Higher TID ratios were associated with higher risk of cardiac death, even after accounting for LVEF-R and MBFR (HR per .1 unit increase = 1.25 (1.11, 1.41), P < .001). This was seen in patients with both normal (HR for TID per .1 unit increase = 1.24 (95% CI: 1.01, 1.52), P = .04) and abnormal perfusion (HR for TID per .1 unit increase = 1.14 (95% CI: 1.02, 1.28), P = .03).
