Attention Score in Context

This research output has an Altmetric Attention Score of 351. 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 16 February 2020.
All research outputs
#35,442
of 14,332,096 outputs
Outputs from CMAJ
#67
of 6,559 outputs
Outputs of similar age
#665
of 223,447 outputs
Outputs of similar age from CMAJ
#2
of 107 outputs
Altmetric has tracked 14,332,096 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 6,559 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 25.4. This one has done particularly well, scoring higher than 98% 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 223,447 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 107 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 98% of its contemporaries.
