Attention Score in Context

This research output has an Altmetric Attention Score of 24412. 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 24 May 2022.

All research outputs

#17

of 21,255,122 outputs

Outputs from The Lancet

of 39,155 outputs

Outputs of similar age

of 305,327 outputs

Outputs of similar age from The Lancet

of 372 outputs

Altmetric has tracked 21,255,122 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 39,155 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 64.4. 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 305,327 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 372 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.
