Attention Score in Context
This research output has an Altmetric Attention Score of 28. 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 24 January 2024.
All research outputs
#1,387,936
of 25,225,182 outputs
Outputs from Canadian Medical Association Journal
#1,809
of 9,391 outputs
Outputs of similar age
#11,323
of 202,825 outputs
Outputs of similar age from Canadian Medical Association Journal
#23
of 99 outputs
Altmetric has tracked 25,225,182 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 94th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 9,391 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 34.0. This one has done well, scoring higher than 80% 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 202,825 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 94% of its contemporaries.
We're also able to compare this research output to 99 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 77% of its contemporaries.
