This research output has an Altmetric Attention Score of 1. 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 15 December 2025.
All research outputs
#20,799,354
of 29,844,540 outputs
Outputs from British Journal of Ophthalmology
#5,246
of 6,739 outputs
Outputs of similar age
#166,678
of 325,013 outputs
Outputs of similar age from British Journal of Ophthalmology
#20
of 55 outputs
Altmetric has tracked 29,844,540 research outputs across all sources so far. This one is in the 20th percentile – i.e., 20% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,739 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.7. This one is in the 14th percentile – i.e., 14% 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 325,013 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 34th percentile – i.e., 34% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 55 others from the same source and published within six weeks on either side of this one. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
