Attention Score in Context
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 21 November 2025.
All research outputs
#22,340,850
of 34,404,538 outputs
Outputs from Proceedings of the National Academy of Sciences of the United States of America
#105,257
of 118,996 outputs
Outputs of similar age
#134,045
of 366,032 outputs
Outputs of similar age from Proceedings of the National Academy of Sciences of the United States of America
#728
of 955 outputs
Altmetric has tracked 34,404,538 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 118,996 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 40.0. This one is in the 10th percentile – i.e., 10% 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 366,032 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 61% of its contemporaries.
We're also able to compare this research output to 955 others from the same source and published within six weeks on either side of this one. This one is in the 21st percentile – i.e., 21% of its contemporaries scored the same or lower than it.
