Postprandial hyperglycemia was ameliorated by taking metformin 30 min before a meal than taking metformin with a meal; a randomized, open-label, crossover pilot study.

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
Taking metformin with a meal has been shown to decrease bioavailability of metformin. We hypothesized that taking metformin 30 min before a meal improves glucose metabolism. As an animal model, 18 Zucker-rats were divided into three groups as follows: no medication (Control), metformin (600 mg/kg) with meal (Met), and metformin 10 min before meal (pre-Met). In addition, five diabetic patients were recruited and randomized to take metformin (1000 mg) either 30 min before a meal (pre-Met protocol) or with a meal (Met protocol). In the animal model, the peak glucose level of pre-Met (7.8 ± 1.5 mmol/L) was lower than that of Control (12.6 ± 2.5 mmol/L, P = 0.010) or Met (14.1 ± 2.9 mmol/L, P = 0.020). Although there was no statistical difference among the three groups, total GLP-1 level at t = 0 min of pre-Met (7.4 ± 2.7 pmol/L) tended to be higher than that of Control (3.7 ± 2.0 pmol/L, P = 0.030) or Met (3.9 ± 1.2 pmol/L, P = 0.020). In diabetic patients, the peak glucose level of pre-Met protocol (7.0 ± 0.4 mmol/L) was lower than that of Met protocol (8.5 ± 0.9 mmol/L, P = 0.021). Total GLP-1 level at t = 30 min of pre-Met protocol (11.0 ± 6.1 pmol/L) was higher than that of Met protocol (6.7 ± 3.9 pmol/L, P = 0.033). Taking metformin 30 min before a meal ameliorated postprandial hyperglycemia. This promises to be a novel approach for postprandial hyperglycemia.
