This research output has an Altmetric Attention Score of 2. 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 23 October 2011.
All research outputs
#13,355,173
of 22,653,392 outputs
Outputs from BMC Pregnancy and Childbirth
#2,472
of 4,144 outputs
Outputs of similar age
#85,008
of 135,957 outputs
Outputs of similar age from BMC Pregnancy and Childbirth
#21
of 32 outputs
Altmetric has tracked 22,653,392 research outputs across all sources so far. This one is in the 39th percentile – i.e., 39% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,144 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.8. This one is in the 38th percentile – i.e., 38% 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 135,957 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 32 others from the same source and published within six weeks on either side of this one. This one is in the 34th percentile – i.e., 34% of its contemporaries scored the same or lower than it.
