#4,821,909
of 28,841,988 outputs
Outputs from New England Journal of Medicine
#20,908
of 35,595 outputs
Outputs of similar age
#23,205
of 132,973 outputs
Outputs of similar age from New England Journal of Medicine
#125
of 230 outputs
Altmetric has tracked 28,841,988 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 35,595 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 119.9. This one is in the 41st percentile – i.e., 41% 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 132,973 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 82% of its contemporaries.
We're also able to compare this research output to 230 others from the same source and published within six weeks on either side of this one. This one is in the 45th percentile – i.e., 45% of its contemporaries scored the same or lower than it.
