Sex-Specific regional brain activity and cognitive function in mild cognitive impairment: An rs-fMRI study.
Article in Translational psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Mild cognitive impairment (MCI) is widely recognized as an early stage of dementia. Epidemiological studies suggest that MCI is more prevalent in females than in males. Notably, there are sex differences in MCI-related brain changes. Resting-state functional magnetic resonance imaging (rs-fMRI) offers a valuable method for assessing brain activity during rest. This study aims to explore sex-specific regional brain activity in participants with MCI during resting states. 86 MCI participants (21 males and 65 females) and 107 normal controls (NCs) (38 males and 69 females) were included in the present study. Regional homogeneity (ReHo), degree centrality (DC), amplitude of low frequency fluctuations (ALFF), and fractional ALFF (fALFF) were used to assess brain activity. MCI females showed increased ReHo values in the right cerebellum inferior compared to NC females and MCI males. However, MCI males exhibited increased ReHo values in the left hippocampus compared to NC males and MCI females. ReHo values in the right cerebellum inferior were associated with visuospatial skills in MCI males, and language function in MCI females. Additionally, ReHo values in the left hippocampus were associated with attention function in MCI females but not in MCI males. In MCI participants, sex moderated the relationship between ReHo values in the right cerebellum inferior and cognitive function (visuospatial skills and language function), as well as the association between ReHo values in the left hippocampus and attention function. In conclusions, this study revealed sex differences in ReHo of right inferior cerebellum and left hippocampus in MCI, and the association between ReHo and cognitive impairment in MCI differs by sex. These sex-specific patterns of regional brain activity can aid in the development of sex-specific precision medicine.
