Effect of food on the pharmacokinetics of omeprazole, pantoprazole and rabeprazole.
Trial report in BMC pharmacology & toxicology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 papers, 1 of them a synthesis that pooled 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.
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
backgroundThe pharmacokinetics of proton pump inhibitors (PPIs) may be affected by food intake. We aimed to evaluate the effect of food on the pharmacokinetics of omeprazole, rabeprazole, and pantoprazole.
settingThe study population comprised 186 healthy volunteers participating in 6 bioequivalence clinical trials.
methodSubjects were evaluated to determine the effect of a high-fat breakfast on the pharmacokinetics of omeprazole (n = 36), rabeprazole (n = 69), and pantoprazole (n = 81).
main outcome measureDrug plasma concentrations were measured using high-performance liquid chromatography coupled to mass spectrometry.
resultsFood affected the pharmacokinetics of omeprazole (increased T
conclusionAs food delays the absorption of PPIs and increases their variability, it would be better to administer these drugs under fasting conditions.
