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 02 October 2026.
All research outputs
#83,015
of 34,575,175 outputs
Outputs from Science
#2,796
of 94,183 outputs
Outputs of similar age
#27
of 52,020 outputs
Outputs of similar age from Science
#2
of 272 outputs
Altmetric has tracked 34,575,175 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 94,183 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 66.2. This one has done particularly well, scoring higher than 97% 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 52,020 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 272 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 99% of its contemporaries.
