This research output has an Altmetric Attention Score of 4. 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 27 May 2013.
All research outputs
#7,794,785
of 25,595,500 outputs
Outputs from Cochrane database of systematic reviews
#9,193
of 13,156 outputs
Outputs of similar age
#61,782
of 205,561 outputs
Outputs of similar age from Cochrane database of systematic reviews
#146
of 211 outputs
Altmetric has tracked 25,595,500 research outputs across all sources so far. This one has received more attention than most of these and is in the 69th percentile.
So far Altmetric has tracked 13,156 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 35.8. This one is in the 29th percentile – i.e., 29% of its peers scored the same or lower than it.
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 205,561 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 69% of its contemporaries.
We're also able to compare this research output to 211 others from the same source and published within six weeks on either side of this one. This one is in the 31st percentile – i.e., 31% of its contemporaries scored the same or lower than it.
