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

backgroundGestational diabetes mellitus (GDM) has a high incidence rate among pregnant women. The objective of the study was to assess the effect of plant-derived oleuropein in attenuating inflammatory and oxidative stress of GDM.

methodsOleuropein was administered to GDM mice at the doses of 5 or 10 mg/kg/day. Body weight, blood glucose, insulin and hepatic glycogen levels were recorded. To evaluate the effect of oleuropein in reducing oxidative stress, ELISA was used to measure the hepatic oxidative stress markers. The inflammation levels of GDM mice were evaluated by measuring serum levels of IL-6 and TNF-α by ELISA and mRNA levels of IL-1β, TNF-α and IL-6 by real-time PCR (RT-PCR). The AMP-activated protein kinase (AMPK) signaling pathway was assessed by Western blot. Gestational outcome was analyzed through comparing litter size and birth weight.

resultsOleuropein attenuated the elevated body weight of GDM mice and efficiently reduced blood glucose, insulin and hepatic glycogen levels. Oxidative stress and inflammation were alleviated by oleuropein treatment. The AMPK signaling was activated by oleuropein in GDM mice. Gestational outcome was markedly improved by oleuropein treatment.

conclusionsOur study suggests that oleuropein is effective in alleviating symptoms of GDM and improving gestational outcome in the mouse model. This effect is achieved by attenuating oxidative stress and inflammation, which is mediated by the activation of the AMPK signaling pathway.
