of 32,632,530 outputs
Outputs from BMJ Open
#18,008
of 28,815 outputs
Outputs of similar age
#248,944
of 444,628 outputs
Outputs of similar age from BMJ Open
#476
of 792 outputs
Altmetric has tracked 32,632,530 research outputs across all sources so far. This one is in the 35th percentile – i.e., 35% of other outputs scored the same or lower than it.
So far Altmetric has tracked 28,815 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 17.9. This one is in the 35th percentile – i.e., 35% 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 444,628 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 792 others from the same source and published within six weeks on either side of this one. This one is in the 37th percentile – i.e., 37% of its contemporaries scored the same or lower than it.
