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

introductionPatients with gastroesophageal reflux disease (GERD) are commonly instructed to reduce coffee intake. However, previous studies evaluating the effects of coffee on GERD yielded conflicting results. We aimed to perform a comprehensive systematic review and meta-analysis to assess the association between coffee use and risk of GERD and its complications.

methodsA protocolized search strategy was developed for PubMed, EMBASE, and Web of Science databases in accordance with preferred reporting items for systematic reviews and meta-analyses and meta-analyses of observational studies in epidemiology guidelines. Measured outcomes for GERD were compared between coffee drinkers and nondrinkers. Dichotomous events between unmatched groups were used to calculate pooled proportions with rates estimated using random effects models and effect size. Heterogeneity was assessed with I2 statistics and publication bias by funnel plot asymmetry and Egger regression.

resultsA total of 40 studies encompassing 122,074 patients were included (85,400 coffee drinkers vs 36,674 nondrinkers). GERD was more common among coffee users than nonusers (34.9% [CI: 28.5-41.8] vs 30.7% [CI: 25.2-36.7]; OR: 1.18 [CI: 1.03-1.36; I 2 = 89.38]). There was no significant association between coffee intake and Barrett's esophagus (22.1% [CI: 12.8-35.4] users vs 17.6% [CI:5.5-43.8] nonusers; OR:1.13 [CI:0.79-1.61; I 2 = 55.5]). There was no evidence of publication bias based on funnel plot and Egger regression testing ( P > 0.05 for all analyses). DISCUSSION: Coffee use was associated with a small, statistically significant increased rate of GERD, but not Barrett's. The magnitude of this effect, however, is of unclear clinical significance. The role of routine avoidance/reduction of coffee intake as universal lifestyle modification for GERD needs further evaluation.
