Pharmacologic Stress Myocardial Perfusion Imaging with SPECT and PET in Liver Transplant Candidates: Physiologic Limitations, Current Evidence, and Future Directions.
Review in Current cardiology reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purpose of reviewMyocardial perfusion imaging with SPECT and PET is commonly used to assess coronary artery disease, but its role in liver transplant candidates remains incompletely defined. This review examines how cirrhotic physiology affects pharmacologic stress imaging and summarizes current evidence for the use of SPECT, PET, and quantitative perfusion measures in this population. RECENT
findingsHyperdynamic circulation, elevated resting myocardial blood flow, impaired chronotropic response, and attenuated vasodilator reserve may reduce the diagnostic performance of relative perfusion imaging. Reported SPECT sensitivity for coronary artery disease in liver transplant candidates is substantially lower than the general population. Quantitative PET, particularly myocardial flow reserve, has shown possible prognostic value, although evidence is limited to small observational cohorts. SPECT should be interpreted cautiously in higher-risk candidates. PET may offer additional physiologic and prognostic information, but transplant-specific thresholds and clinical pathways remain unvalidated. Whether improved perfusion-based risk stratification changes management and improves outcomes remains to be determined.
