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

Depressive symptoms are common in individuals with mild cognitive impairment (MCI) and may contribute to an increased risk of dementia. However, the neuroanatomical correlates and underlying pathophysiological mechanisms of depressive symptoms in MCI remain largely unknown. We aimed to elucidate alterations in gray matter volume and the related molecular and genetic bases in MCI patients with depressive symptoms. A total of 177 participants were enrolled, comprising 57 MCI patients with depressive symptoms (D-MCI), 60 MCI patients without depressive symptoms (nD-MCI), and 60 healthy controls (HCs). Gray matter morphological differences among groups were examined using voxel-based morphometry. The associations between depressive symptom-related morphological alterations and functional characteristics, neurotransmitter distributions, and gene expression profiles were further investigated. Group comparisons revealed depressive symptom-related morphological alterations in the inferior frontal gyrus, precentral gyrus, and anterior cingulate cortex, with the associated functional terms strongly linked to "emotions" and "affective." These alterations were further correlated with serotonergic, dopaminergic, and GABAergic systems and the expression of specific genes implicated in synaptic function and excitatory neurons. This study demonstrated the molecular and transcriptional underpinnings of brain morphological alterations linked to depressive symptoms in MCI, which may provide deeper insight into this condition.
