Age-related loss of large dendritic spines in the precuneus is statistically mediated by proteins which are predicted targets of existing drugs.

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
Preservation of dendritic spines is a putative mechanism of protection against cognitive impairment despite development of Alzheimer Disease (AD)-related pathologies. Aging, the chief late-onset AD risk factor, is associated with dendritic spine loss in select brain areas. However, no study to our knowledge has observed this effect in precuneus, an area selectively vulnerable to early accumulation of AD-related pathology. We therefore quantified dendritic spine density in precuneus from 98 subjects without evidence of neurocognitive decline, spanning ages 20-96, and found a significant negative correlation between age and large dendritic spine density. In these same subjects, we conducted liquid chromatography-tandem mass spectrometry of >5000 proteins and identified 203 proteins which statistically mediate the effect of age on large dendritic spine density. Using computational pharmacology, we identified ten drugs which are predicted to target these mediators, informing future studies designed to test their effects on age-related dendritic spine loss and cognitive decline.
