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

Brain-derived neurotrophic factor (BDNF) plays a pivotal role in learning and memory, and reductions in BDNF levels are closely associated with cognitive decline and psychiatric disorders. Dietary factors that maintain or restore brain BDNF expression may therefore contribute to brain health. In this study, we evaluated the effects of heat-killed lactic acid bacteria (LAB) on scopolamine-induced BDNF reduction using Bdnf-Luciferase (Bdnf-Luc) transgenic mice, which allow noninvasive monitoring of BDNF expression in the living brain by in vivo bioluminescence imaging. Administration of scopolamine induced a significant reduction in brain BDNF expression, which was successfully visualized by bioluminescence imaging. Oral administration of heat-killed Bifidobacterium longum KABP-042 markedly prevented this reduction, while heat-killed Lactiplantibacillus plantarum KABP-051 showed partial protective effects. Furthermore, both LAB strains significantly ameliorated scopolamine-induced impairment of hippocampus-dependent memory in contextual fear conditioning. These results demonstrate that specific heat-killed LAB exert protective effects against BDNF reduction and cognitive dysfunction in vivo. In addition, our findings highlight the utility of Bdnf-Luc-based in vivo bioluminescence imaging as a practical tool for evaluating dietary factors with potential benefits for brain health.
