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

purposeElevated methylglyoxal (MGO) levels and altered immune cell responses are observed in diabetes. MGO is thought to modulate immune cell activation. The current study investigated whether fasting or post-glucose-load plasma MGO concentrations are associated with circulating immune cell counts and activation in a large cohort study.

methods696 participants of The Maastricht Study (age 60.3 ± 8.4 years, 51.9% women) underwent an oral glucose tolerance test (OGTT). Fasting and post-OGTT plasma MGO concentrations were measured using mass spectrometry. Numbers and activation of circulating immune cells at fasting state were quantified using flow cytometry. Activation scores were calculated by averaging individual marker z-scores for neutrophils (CD11b, CD11c, CD16) and classical, intermediate, and non-classical monocytes (CD11b, CD11c, CX3XR1, HLA-DR). Associations were analysed using multiple linear regression adjusted for potential confounders. Stratified analyses were performed for glucose metabolism status for associations between plasma MGO levels and immune cell counts.

resultsHigher fasting plasma MGO concentrations were significantly associated with higher numbers of intermediate (β = 0.09 [95%CI 0.02; 0.17]) and non-classical monocytes (0.08 [0.002; 0.15]), but with lower activation scores for the intermediate monocytes (-0.14 [-0.22; -0.06]). Stratified analyses showed that positive associations between fasting plasma MGO levels and numbers of intermediate and non-classical monocytes appear only in participants with type 2 diabetes. Post-OGTT plasma MGO concentrations were not consistently associated with immune cells counts or activation.

conclusionHigher fasting plasma MGO concentrations are associated with higher intermediate and non-classical monocyte counts but with lower activation of intermediate monocytes.
