#19,314,902
of 29,631,763 outputs
Outputs from BMJ Open
#18,983
of 28,140 outputs
Outputs of similar age
#211,801
of 360,380 outputs
Outputs of similar age from BMJ Open
#645
of 876 outputs
Altmetric has tracked 29,631,763 research outputs across all sources so far. This one is in the 32nd percentile – i.e., 32% of other outputs scored the same or lower than it.
So far Altmetric has tracked 28,140 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 18.0. This one is in the 29th percentile – i.e., 29% 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 360,380 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 38th percentile – i.e., 38% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 876 others from the same source and published within six weeks on either side of this one. This one is in the 23rd percentile – i.e., 23% of its contemporaries scored the same or lower than it.
