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

Proton pump inhibitors and clopidogrel are commonly prescribed medications, both alone and in combination. In January of 2009 the US Food and Drug Administration and the European Medicines Agency issued warnings with regard to the concomitant use of clopidogrel and proton pump inhibitors. Later that year, these warnings were limited to the proton pump inhibitor omeprazole. These warnings were largely based on in-vitro studies and observational analyses suggesting decreased efficacy of clopidogrel in the presence of proton pump inhibitors. Recent literature has suggested there may not be a clinically meaningful interaction.
