Burden of premature ventricular contractions beyond nonsustained ventricular tachycardia is related to the myocardial extracellular space expansion in patients with hypertrophic-cardiomyopathy.
Article in Clinical cardiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
backgroundAlthough nonsustained ventricular tachycardia (NSVT) is a risk factor for sudden cardiac death in hypertrophic-cardiomyopathy (HCM), the impact of premature ventricular contraction (PVC) burden, in the absence of NSVT, is not well-known. HYPOTHESIS: PVC burden may be associated with myocardial fibrosis and genetic mutations in patients with HCM.
methodsOf the 212 patients prospectively enrolled to the HCM registry of genetics, 84 were evaluated with both cardiac magnetic resonance, 24-hour Holter monitoring and genetic analysis. Among them, 71 patients have not been diagnosed with NSVT.
resultsPatients with NSVT (n = 13) had a higher late gadolinium enhancement (LGE) amount, extracellular volume fraction (ECV), and prevalence of sarcomere mutations compared with patients without NSVT. Among patients without NSVT, those with LGE (n = 46) had a higher total PVC (109 ± 332 vs 7 ± 13, P = .003) and PVC burden (0.114 ± 0.225 vs 0.008 ± 0.014%, P = .003) during 24-hour Holter monitoring compared with others. The %LGE and global ECV were correlated with PVC burden (r = 0.377, P = .001; r = 0.401, P = .001). The optimal cutoff value for PVC number for LGE was 45 (37.0% and 100% sensitivity and specificity, respectively) with 0.733 of the area under the receiver operating characteristic-curve (P < .001). Thick filament gene mutation was more prevalent in the higher PVC burden group (41.2% vs 16.7%, P = .048).
conclusionTotal PVC burden is significantly related to increase in myocardial fibrosis in HCM patients without NSVT.
