Effects of Omega-3 Fatty Acids on Resting Cerebral Perfusion in Patients with Mild Cognitive Impairment: A Randomized Controlled Trial.
Trial report in The journal of prevention of Alzheimer's disease, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 3 of them syntheses that pooled 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.
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
Alteration of cerebral perfusion can be considered as a possible therapeutic target in mild cognitive impairment. This randomized, placebo-controlled, double-blind proof-of-concept study assessed effects of omega-3 fatty acids on cerebral perfusion in patients with mild cognitive impairment. In thirteen patients (omega:n=5; placebo:n=8) cerebral perfusion was measured before and after 26-weeks intervention within posterior cortical regions using magnetic resonance imaging. There was a medium effect of intervention on cerebral blood flow (η2=0.122) and blood volume (η2=0.098). The omega group showed an increase in blood flow (mean difference: 0.02 [corresponds to 26.1%], 95% confidence interval:0.00-0.05) and blood volume (mean difference: 0.08 [corresponds to 18.5%], 95% confidence interval:0.01-0.15), which was not observed in the placebo group. These preliminary findings suggest that omega-3 fatty acids supplementation may improve perfusion in cerebral regions typically affected in mild cognitive impairment.Regulation of perfusion may help to maintain brain structure and function and potentially delay conversion to dementia.
