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 September 2021.
All research outputs
#2,442,295
of 25,411,814 outputs
Outputs from British Medical Journal
#21,003
of 64,530 outputs
Outputs of similar age
#11,187
of 189,240 outputs
Outputs of similar age from British Medical Journal
#38
of 177 outputs
Altmetric has tracked 25,411,814 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 90th percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 64,530 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 45.2. This one has gotten more attention than average, scoring higher than 67% 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 189,240 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 94% of its contemporaries.
We're also able to compare this research output to 177 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 78% of its contemporaries.
