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

objectiveTo investigate the anti-hypoxia effects of walnut oligopeptides (WOPs) in mice.

methodsRandomly divide the mice into 4 experimental sets. Then randomly divide each set of mice into 5 groups, including one vehicle control group, one whey protein group (220 mg/kg), and three WOPs intervention groups (110 mg/kg, 220 mg/kg, 440 mg/kg). Test substances were administered orally to mice via the drinking water for 30 days.

resultsWOPs significantly extended the normobaric hypoxia survival time, sodium nitrite toxicosis survival time, and acute cerebral ischemia survival time. Notably, WOPs increased red blood cell (RBC), hemoglobin (Hb) and hematocrit (Hct) levels, decreased malonaldehyde (MDA) content and lactate content in brain, enhanced brain lactate dehydrogenase (LDH) activity, and promoted the expression levels of hypoxia-inducible factor 1alpha (HIF1α) mRNA and vascular endothelial growth factor (VEGF) mRNA.

conclusionWOPs have anti-hypoxia effects, and the mechanism may involve the following aspects: the first is to improve the blood's oxygen carrying capacity and oxygen utilization rate, the second is to minimize the lesion of lipid peroxidation, the third is to increase the brain's ability to buffer against lactic acidosis of mice, and the fourth is to promote angiogenesis and regulate hypoxia response.
