This research output has an Altmetric Attention Score of 2. 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 28 April 2012.
All research outputs
#22,312,374
of 34,360,257 outputs
Outputs from JAMA: Journal of the American Medical Association
#36,563
of 42,269 outputs
Outputs of similar age
#145,559
of 212,295 outputs
Outputs of similar age from JAMA: Journal of the American Medical Association
#205
of 303 outputs
Altmetric has tracked 34,360,257 research outputs across all sources so far. This one is in the 33rd percentile – i.e., 33% of other outputs scored the same or lower than it.
So far Altmetric has tracked 42,269 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 73.2. This one is in the 12th percentile – i.e., 12% 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 212,295 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 30th percentile – i.e., 30% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 303 others from the same source and published within six weeks on either side of this one. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
