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

This study evaluated the effects of magnesium (Mg) supplementation on glycaemic control in type 2 diabetes mellitus through a meta-analysis of 23 randomised controlled trials involving 1,345 participants. Mg supplementation significantly increased serum Mg levels (weighted mean difference [WMD] = 0.69, 95% CI: 0.32 to 1.06) and reduced fasting blood glucose levels (WMD = -0.58, 95% CI: -0.87 to -0.28). However, the impact on glycated haemoglobin was minimal (WMD = -0.16, 95% CI: -0.32 to 0.00). Subgroup analysis showed a greater reduction in glycated haemoglobin among participants aged ≥65 years and those receiving longer durations of supplementation. Additionally, Mg supplementation was linked to lower diastolic blood pressure and potential improvements in lipid profile. This review highlights the importance of considering patient characteristics, dosage and intervention duration in future research on Mg supplementation for glycaemic control in diabetes.
