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

objectivesVisceral hypersensitivity is involved in the etiology of reflux symptoms. Familial clustering and twin studies demonstrated a genetic predisposition to gastroesophageal reflux disease (GERD). G-protein-coupled receptors (GPCRs) mediate the response to acid, neurotransmitters and humoral factors modulating esophageal sensory function. Thus, polymorphisms in G-proteins are putative genetic factors contributing to GERD manifestation. A functional polymorphism in the G-protein beta3 subunit gene (GNB3) is associated with functional dyspepsia (FD), in which visceral hypersensitivity is implicated in symptom generation. We evaluated the association of the GNB3 C825T polymorphism with GERD and GERD subgroups classified according to esophageal acid exposure time, symptom-reflux correlation, or coexistence of FD and/or irritable bowel syndrome (IBS) symptoms.

methodsIn total, 363 GERD patients, defined as having esophageal pH < 4 > or = 6% of time and/or symptom index (SI) > or = 50% or symptom association probability (SAP) > or = 95%, participated. In addition, 373 healthy controls free of gastrointestinal symptoms were studied. Genotyping was performed by molecular beacon assay.

resultsThe CT genotype was more prevalent in GERD patients relative to healthy controls (adjusted odds ratio (OR)=1.43, 95% CI 1.04-1.98). GERD patients sensitive to physiological amounts of reflux displayed a higher OR (1.59), as did GERD patients with a positive symptom association score (1.50). The strongest association was detected in patients without concomitant FD and/or IBS symptoms (OR=1.66).

conclusionsGERD is associated with GNB3 C825T. The results for GERD subgroups support the hypothesis that enhanced perception of reflux events, as a consequence of the increased signal transduction upon GPCR activation associated with the 825T allele, underlies this association.
