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

Maternal obesity is known to increase the likelihood of offspring becoming obese, high blood pressure, and other metabolic disorders. After inducing obesity, the effect of treadmill exercise in maternal rats during pregnancy on short-term memory was investigated in relation to neurogenesis in rat pups. Short-term memory was declined in rat pups born to obese maternal rats, and treadmill running during pregnancy alleviated short-term memory impairment in rat pups born to obese maternal rats. The number of doublecortin (DCX)-positive and 5-bro-mo-2'-deoxyuridine (BrdU)-positive cells in the hippocampal dentate gyrus was decreased in rat pups born to obese maternal rats. Treadmill running during pregnancy increased the number of DCX-positive and BrdU-positive cells in rat pups born to obese maternal rats. Expression of brain-derived neurotrophic factor (BDNF) and tyrosine kinase B (TrkB) in the hippocampus was decreased in the rat pups born to obese maternal rats. Treadmill running during pregnancy increased the expressions of BDNF and TrkB in rat pups born to obese maternal rats. Enhancing effect of short-term memory by treadmill exercise may be due to increased neurogenesis through activation of the BDNF-TrkB signaling pathway by treadmill exercise.
