This research output has an Altmetric Attention Score of 3. 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 20 May 2014.
All research outputs
#12,374,117
of 34,454,098 outputs
Outputs from Proceedings of the National Academy of Sciences of the United States of America
#83,818
of 119,070 outputs
Outputs of similar age
#75,587
of 234,501 outputs
Outputs of similar age from Proceedings of the National Academy of Sciences of the United States of America
#475
of 664 outputs
Altmetric has tracked 34,454,098 research outputs across all sources so far. This one is in the 38th percentile – i.e., 38% of other outputs scored the same or lower than it.
So far Altmetric has tracked 119,070 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 40.1. This one is in the 13th percentile – i.e., 13% 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 234,501 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 664 others from the same source and published within six weeks on either side of this one. This one is in the 10th percentile – i.e., 10% of its contemporaries scored the same or lower than it.
