Methylglyoxal Mediates the Association Between 2-Hour Plasma Glucose and HbA1c With Inflammation: The Maastricht Study.
Article in The Journal of clinical endocrinology and metabolism, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
contextGlucose excursions in persons with diabetes may drive chronic inflammation. Methylglyoxal (MGO) is formed from glucose, is elevated in persons with diabetes, and is a potent glycating agent linked with inflammation.
objectiveWe investigated whether glucose excursions are associated with low-grade inflammation and whether MGO mediates this association.
methodsWe used data from The Maastricht Study, an extensive phenotyping study into the etiology of type 2 diabetes and its complications. Data of 3017 participants, who underwent an oral glucose tolerance test and where data on MGO levels and inflammation were available, were used. Linear regression analyses, adjusted for potential confounders, evaluated associations between fasting plasma glucose (FPG), 2-hour plasma glucose (2h-PG) and HbA1c, and low-grade inflammation (stdβ, [95% CI]) were calculated from plasma concentrations of C-reactive protein, serum amyloid A, interleukin-6, interleukin-8, tumor necrosis factor, and soluble intercellular adhesion molecule-1. Mediation analyses investigated whether MGO mediated these associations.
results2h-PG (0.172, [0.110; 0.234]) and HbA1c (0.148, [0.101; 0.196]), but not FPG (0.049, [-0.002; 0.100]), were associated with low-grade inflammation. 2h-PG and HbA1c were also associated with 2h-MGO (0.471, [0.407; 0.534], and 0.244, [0.195; 0.294], respectively). Furthermore, 2h-MGO was independently and positively associated with low-grade inflammation (0.078, [0.037; 0.120]). 2h-MGO mediated 23% of the association between 2h-PG and inflammation, and 16% of the association between HbA1c and inflammation.
conclusionMGO mediates the association between postload glucose excursions and HbA1c with inflammation, providing evidence for a role of postprandial MGO formation to hyperglycemia-induced low-grade inflammation.
