Sex differences in middle-aged and old Wistar rats in response to long-term sulforaphane treatment for prevention of neuroinflammation, cognitive decline and brain senescence.
Article in Biogerontology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
The nervous system (NS) experiences morphological and functional changes during the aging process, where low-grade chronic inflammation, oxidative stress and senescence are key regulators. Sulforaphane (SFN) is an isothiocyanate that activates redox response and inhibits the inflammatory process, which could modify the pro-inflammatory components of senescent cells secretory phenotype (SASP). Here we aimed to determine if SFN long-term treatment was able to prevent age-associated damage in the NS of adult and old females and males Wistar rats. We evaluated cytokines and chemokines profile, senescent cells markers, and memory parameters of adult (15 m.o.) and old (21 m.o.) rats after three months of SFN treatment. Young rats (4 m.o.) were used as age controls. Differences between sexes were observed in the inflammatory profile. Our results showed that SFN-treatment diminished proinflammatory molecules, senescence markers and senescent cells number in brain cortex and hippocampus from males and females' adult rats, but no effects were observed in both sexes old groups compared with the same age control groups. SFN-dependent reduction in inflammatory and senescence parameters resulted in better scores in Barnes Maze Trial memory test when compared with same age non-treated group. Interestingly, adult females showed higher levels of proinflammatory cytokines and chemokines than adult males, which were prevented by SFN-treatment. No effects of SFN were observed in memory of old-treated groups.
