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

Current perspectives on the molecular underpinnings of major depressive disorder (MDD) posit a mechanistic role of epigenetic DNA modifications in mediating the interaction between environmental risk factors and a genetic predisposition. However, conclusive evidence for differential methylation signatures in the brain's epigenome of MDD patients as compared to controls is still lacking. To address this issue, we conducted a pilot study including an epigenome-wide methylation analysis in six individuals diagnosed with recurrent MDD and six control subjects matched for age and gender, with a priori focus on the hippocampus and prefrontal cortex as pathophysiologically relevant candidate regions. Our analysis revealed differential methylation profiles of 11 genes in hippocampus and 20 genes in prefrontal cortex, five of which were selected for replication of the methylation status using pyrosequencing. Among these replicated targets, GRIN2A was found to be hypermethylated in both prefrontal cortex and hippocampus. This finding may be of particular functional relevance as GRIN2A encodes the glutamatergic N-methyl-D-aspartate receptor subunit epsilon-1 (NR2A) and is known to be involved in a plethora of synaptic plasticity-related regulatory processes probably disturbed in MDD.
