Correlation of left ventricular dyssynchrony on gated myocardial perfusion SPECT analysis with extent of late gadolinium enhancement on cardiac magnetic resonance imaging in hypertrophic cardiomyopathy.
Article in Heart and vessels, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Myocardial perfusion-single-photon emission computed tomography (MP-SPECT) is used to evaluate microvascular dysfunction and coexisting coronary artery disease in patients with hypertrophic cardiomyopathy (HCM). Phase analysis in gated MP-SPECT can provide additional information on left ventricular (LV) dyssynchrony, while the extent of late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) imaging is an important prognostic factor in patients with HCM. We, therefore, sought to investigate the relationship of dyssynchrony by phase analysis on gated MP-SPECT and LGE on CMR imaging in 22 patients with HCM who underwent both stress/rest-gated MP-SPECT and contrast-enhanced CMR imaging. LV dyssynchrony parameters [phase standard deviation (SD) and histogram bandwidth] from gated MP-SPECT were compared with LGE parameters from CMR imaging [L/C contrast and %LGE calculated, respectively, as LGE intensity/LV cavity intensity and (LGE volume/myocardial volume) × 100]. Phase SD and histogram bandwidth showed strong correlation with %LGE (r = 0.73, p < 0.0001 and r = 0.73, p < 0.0001, respectively), although they did not significantly correlate with L/C contrast (r = 0.30, p = 0.17 and r = 0.26, p < 0.25, respectively). The LV dyssynchrony derived from gated MP-SPECT strongly correlated with the extent of LGE on CMR imaging. In conclusion, our investigation suggests that gated MP-SPECT may be useful not only for the assessment of myocardial ischemia but also the extent of myocardial replacement fibrosis.
