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

Overeating highly palatable foods typical of a Western diet (WD) has been linked to cognitive impairments in animal models and humans. Exercise training was proposed as an important behavioral intervention with beneficial effects, including improving peripheral insulin sensitivity, improving central functions such as learning and memory, and restoring a dysregulated blood-brain barrier (BBB). The purpose of the present study was to characterize the effect of exercise training in rats fed with the WD with special emphasis on BBB. Adult female Long Evans rats were subjected to 12 weeks of WD feeding (WD group), or simultaneous WD feeding and wheel-running training (WD/EX group), or were fed a WD for 6 weeks without training and then subjected to diet and training for an additional 6 weeks (WD_WD/EX group). A sedentary (untrained) group of lean rats was fed a standard rodent chow (CTR group). In all experimental groups, we measured behavioral and physiological parameters, and the hippocampal levels of proteins structurally and functionally related to BBB, including proinflammatory cytokines and products of elevated lipid peroxidation. Exercise training in combination with a WD decreased locomotor and exploratory activities and induced short-term memory impairments. The behavioral changes were accompanied by reduced levels of occludin, claudin-5, and ZO-1 proteins in the hippocampus, suggesting changes in the integrity and increased permeability of BBB. In the WD_WD/EX rats, we found increased hippocampal levels of malondialdehyde (MDA) and neurotrophins (Bdnf, Vegfa) suggesting that increased energy expenditure by obese rats stimulates endogenous protective processes. The training introduced after 6 weeks of WD feeding in rats showing an obese phenotype may suggest that the sequence and moment of presumably protective intervention (exercise training) could alleviate or, on the contrary, exacerbate the level of stress and its consequences.
