Attention Score in Context

This research output has an Altmetric Attention Score of 16. 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 06 July 2018.
All research outputs
#969,626
of 13,187,018 outputs
Outputs from BMC Medical Research Methodology
#145
of 1,212 outputs
Outputs of similar age
#938,406
of 12,563,844 outputs
Outputs of similar age from BMC Medical Research Methodology
#145
of 1,209 outputs
Altmetric has tracked 13,187,018 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 92nd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,212 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.8. This one has done well, scoring higher than 88% 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 12,563,844 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 92% of its contemporaries.
We're also able to compare this research output to 1,209 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 88% of its contemporaries.
