Attention Score in Context

This research output has an Altmetric Attention Score of 153. 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 26 September 2019.
All research outputs
#95,890
of 13,611,781 outputs
Outputs from JAMA: Journal of the American Medical Association
#1,880
of 25,945 outputs
Outputs of similar age
#93,453
of 12,937,396 outputs
Outputs of similar age from JAMA: Journal of the American Medical Association
#1,875
of 24,434 outputs
Altmetric has tracked 13,611,781 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 99th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 25,945 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 47.9. This one has done particularly well, scoring higher than 92% 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 12,937,396 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 99% of its contemporaries.
We're also able to compare this research output to 24,434 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 92% of its contemporaries.
