Attention Score in Context

This research output has an Altmetric Attention Score of 1479. 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 April 2023.

All research outputs

#7,212

of 23,934,148 outputs

Outputs from Science Advances

#101

of 10,670 outputs

Outputs of similar age

#357

of 439,522 outputs

Outputs of similar age from Science Advances

of 507 outputs

Altmetric has tracked 23,934,148 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 10,670 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 121.3. This one has done particularly well, scoring higher than 99% 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 439,522 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 507 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 98% of its contemporaries.
