DNA methylation dysregulations in rheumatic heart valve disease.
Article in BMC cardiovascular disorders, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
backgroundThe epigenetic changes underlying the development of rheumatic heart valve disease (RHVD) remain incompletely understood. Limited evidence suggests that abnormal DNA methylation might be involved in the pathogenesis of RHVD. In the present study, we evaluated the DNA methylation dysregulations from myocardial tissue in RHVD patients systematically.
methodsRight atrial myocardial tissue obtained from rheumatic valvular patients who had undergone valve replacements surgery (n = 73) and were compared to healthy controls (n = 4). the promoter methylation level of Intercellular adhesion molecule-1 (ICAM-1) gene and its correlation with ICAM-1 mRNA expression level, the global DNA methylation level and its correlation with age and mRNA expression level of DNA methyltransferase (DNMT) genes were detected.
resultsThe ICAM-1 mRNA expression was increased (healthy control vs. NHYA III, 0.70 ± 0.19 vs. 4.38 ± 3.19, p = 0.011; NYHA IIvs. NHYA III, 2.60 ± 1.99 vs. 4.38 ± 3.19, p = 0.008) and the ICAM-1 gene was hypomethylated in RHVD patients (healthy controls vs. NYHA II, 0.120 ± 0.011 vs. 0.076 ± 0.057, p = 0.039; healthy control vs. NHYA III, 0.120 ± 0.011 vs. 0.041 ± 0.022, p < 0.001; NYHA IIvs. NHYA III, 0.076 ± 0.057 vs. 0.041 ± 0.022, p < 0.001). Meanwhile, The ICAM-1 mRNA expression level has negative correlation with the mean methylation level in the promoter region of ICAM-1 gene (r = -0.459, p < 0.001). The global DNA methylation levels was significantly increased in RHVD patients than in healthy controls (healthy control vs. NHYA III, 0.77 ± 0.28 vs. 2.09 ± 1.20, p = 0.017; NYHA IIvs. NHYA III, 1.57 ± 0.78 vs. 2.09 ± 1.20, p = 0.040) and had positive correlation with age (r = 0.326, p = 0.005), especially for older age group (≥ 60 years). DNMT1 likely plays an essential role in the DNA dysregulations in RHVD patients.
conclusionsOur analysis revealed that DNA methylation dysregulations may be relevant in the pathogenesis of RHVD.
