1 · What the graph read from 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.

2 · The registry

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

The catechol-O-methyl transferase (COMT) 158Val/Met variant has been suggested to play a role in COMT function. Epigenetic regulation of COMT may further influence the prevalence of metabolic syndrome in these patient populations. This study examined the correlation between COMT promoter methylation and metabolic syndrome in schizophrenia patients receiving atypical antipsychotic (AAP) therapy. DNA was extracted from peripheral blood samples of schizophrenia subjects screened for metabolic syndrome. Pyrosequencing was used to analyze two methylation sites of the soluble COMT (COMT-s) promoter region. Associations between AAP use, lifestyle variables, metabolic syndrome and COMT genotype with peak methylation values were analyzed. Data are reported in 85 subjects. Methylation on CpG site 1 had a mean of 79.08% (±4.71) and it was 12.43% (±1.19) on site 2. COMT genotype proved to be an indicator of COMT methylation status on site 1 (F(2, 84)=5.78, P=0.0044) and site 2 (F(2, 84),=3.79, P=0.027). A significant negative correlation between physical activity and COMT promoter region methylation was found in Val/Val homozygous patients (site 1: P=0.013 and site 2: P=0.019). Those homozygous for Met/Met showed a positive correlation between promoter site methylation and physical activity (site 1: P=0.027, site 2: P=0.005), and between CpG site methylation and metabolic syndrome (site 1: P=0.002; site 2: P=0.001). The results of this study suggest that COMT promoter region methylation is largely influenced by COMT genotype and that physical activity plays a significant role in epigenetic modulation of COMT.
