This research output has an Altmetric Attention Score of 1. 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 08 October 2025.
All research outputs
#28,485,094
of 34,259,606 outputs
Outputs from Proceedings of the National Academy of Sciences of the United States of America
#113,729
of 118,656 outputs
Outputs of similar age
#246,504
of 348,052 outputs
Outputs of similar age from Proceedings of the National Academy of Sciences of the United States of America
#721
of 783 outputs
Altmetric has tracked 34,259,606 research outputs across all sources so far. This one is in the 9th percentile – i.e., 9% of other outputs scored the same or lower than it.
So far Altmetric has tracked 118,656 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 39.8. This one is in the 2nd percentile – i.e., 2% 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 348,052 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 15th percentile – i.e., 15% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 783 others from the same source and published within six weeks on either side of this one. This one is in the 3rd percentile – i.e., 3% of its contemporaries scored the same or lower than it.
