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

AIMS/

introductionType 2 diabetes is characterized by dysregulation of immunity, oxidative stress and reduced incretin effects. Experimental studies suggest that glucagon-like peptide (GLP-1) might have immunomodulating effects. We hypothesize that GLP-1 receptor agonist, exendin-4, might reduce inflammatory response in type 2 diabetes. MATERIALS AND

methodsUsing peripheral blood mononuclear cells (PBMC) sampled from 10 type 2 diabetes and 10 sex- and age-matched control subjects and supernatants from PBMC culture, the expression of phospho-mitogen activated protein kinase (MAPK) signaling pathways in CD4+ T helper lymphocytes and monocytes was analyzed using flow cytometry. Cytokines/chemokines and superoxide anion before and after treatment with exendin-4 were measured by cytometric bead array and chemiluminesence assay, respectively.

resultsCompared with control subjects, PBMC from type 2 diabetes patients showed activated MAPK (P38, c-Jun NH2-terminal protein kinase and extracellular signal-regulated kinase) signaling pathway, elevated superoxide anion, increased pro-inflammatory cytokines (tumor necrosis factor-α, interleukin-1β, interleukin-6) and chemokines (CCL5/regulated on activation normal T-cell expressed and secreted and CXCL10/interferon-γ-induced protein 10). These changes were attenuated by exendin-4, possibly through the suppression of p38 MAPK.

conclusionsThese results suggest that exendin-4 might downregulate pro-inflammatory responses and reduce oxidative stress by suppressing MAPK signaling pathways in type 2 diabetes.
