| Abstract |
Evidence has demonstrated that omega-3 fatty acids intake may be associated with age-related cognitive decline. However, randomized controlled trials (RCTs) have drawn inconsistent conclusions. We performed a meta-analysis to assess the association between omega-3 fatty acids and risk of cognitive decline in the elderly. A strategic literature search of PubMed, EMBASE, and Cochrane Library (updated to December 2014) was performed. We retrieved six randomized controlled studies as eligible for our meta-analysis. Among these six studies, the duration time ranged from 3 to 40 months. The dose of omega-3 fatty acids (DHA + EPA) ranged from 400 to 1800 mg. The result of our meta-analysis expressed that omega-3 fatty acids statistically decrease the rate of cognitive decline in MMSE score (WMD = 0.15, [0.05, 0.25]; p = 0.003). In conclusion, our meta-analysis indicated that omega-3 fatty acids may help to prevent cognitive decline in the elderly. |

Attention Score in Context
This research output has an Altmetric Attention Score of 25. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 September 2022.
All research outputs
#1,545,000
of 25,373,627 outputs
Outputs from Aging Clinical and Experimental Research
#82
of 1,867 outputs
Outputs of similar age
#19,178
of 280,686 outputs
Outputs of similar age from Aging Clinical and Experimental Research
#1
of 21 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 93rd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,867 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 7.9. This one has done particularly well, scoring higher than 95% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 280,686 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 93% of its contemporaries.
We're also able to compare this research output to 21 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 95% of its contemporaries.
