Effects of food on pharmacokinetics and safety of metformin hydrochloride tablets: A meta-analysis of pharmacokinetic, bioavailability, or bioequivalence studies.
Article in Heliyon, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Background: The effects of food on the pharmacokinetics and safety of metformin hydrochloride (MH) are unclear. Objective: To discover the effects of food on the pharmacokinetics and safety of MH, and its influence factors. Methods: English and Chinese databases, and grey (unpublished) literature were searched for eligible studies (registration No. CRD 42022321067 in PROSPERO network). The summary weighted mean difference for continuous variables, and the risk ratio for dichotomous variables was calculated for the main pharmacokinetic parameters. Heterogeneity among the included studies was analyzed using the Results: Fourteen clinical trials were included, comprising 408 participants. The pooled AUC Conclusions: Pharmacokinetics parameters of MH were affected by food. High-fat, high-calorie diet lowered the extent and rate of absorption while slowing the absorption of metformin. These findings suggest that it is necessary to increase the dosage of MH in order to maintain the same treatment effect when administration of MH after a high fat, high calorie diet.
