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

objectivesPrenatal stresses increase incidence of neurodevelopmental disorders and influence cognitive abilities. Glucocorticoids are released in stress condition as endpoint activation of hypothalamus-pituitary-adrenal (HPA) axis. Evidence indicates a cross-talk between gut microbiota and brain function. This study assesses the effect of probiotic supplementation on behavioral functionand HPA axis action in stressed rats. MATERIALS AND

methodsThe young rats born from dams exposed to noise stress (ST) during third trimester of pregnancy were used. Two groups of stressed animals were received a two-week probiotic supplementation before (pre-ST) and after (post-ST) birth. The time and distance to find hidden platform in Morris water maze were evaluated as spatial memory. Also entry to open arms in elevated plus-maze was considered as anxiety-like behaviors. The serum level of corticosterone was measured as the HPA axis function.

resultsWhile the stressed rats decreased entries to open arms to one third compared to the controls (CON) the probiotic treatment increased the entries by two times. The ST rats required more time and distance to find the platform than did the CON animals. The pre- and post-ST rats significantly restored the impaired behavior almost near the CON ones. While the serum corticosterone concentration increased by 50% in the ST rats it was reduced to almost normal level in the pre- and post-ST rats.

conclusionOur findings confirmed a link between the gut microbiome and probiotics with the behavioral functions and HPA axis. The probiotic treatment favorably affected the stress-dependent behavioral disorders and the interaction between HPA and gut-brain-microbiota axes.
