Evidence-based medicine relies on current best evidence from the medical literature, the patient's history, and the clinician's own experience to provide the best care for patients. Systematic reviews and meta-analysis are considered the highest levels of evidence for informing clinical decisions. Recently, reports have shown an increase in the number but a decrease in quality of meta-analysis publications. We reviewed publication trends and determined the countries with the most journal articles and types of publications in PubMed from 1995 to 2015. We examined journal entries in PubMed from 1995 to 2015 from top publishing countries for total number of publications and citations in core clinical journals and in specific publication types (systematic reviews, meta-analysis, randomized controlled trials). Yearly, only 30 countries generated 94.6% of all publications and 98.1% of core clinical journals worldwide. All publication types increased but with a significant increase in meta-analysis publications from China. Collaborative and co-authored papers among the 30 countries also showed an increasing trend. The USA leads in all publication citations and specific publication types, except for meta-analysis where China publishes more. Collaborative publishing among international collaborators is also increasing.

Attention Score in Context

This research output has an Altmetric Attention Score of 8. 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 28 August 2021.
All research outputs
of 20,362,325 outputs
Outputs from Systematic Reviews
of 1,788 outputs
Outputs of similar age
of 293,614 outputs
Outputs of similar age from Systematic Reviews
of 1 outputs
Altmetric has tracked 20,362,325 research outputs across all sources so far. Compared to these this one has done well and is in the 82nd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,788 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 12.7. This one has gotten more attention than average, scoring higher than 59% of its peers.
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 293,614 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 76% of its contemporaries.
We're also able to compare this research output to 1 others from the same source and published within six weeks on either side of this one. This one has scored higher than all of them
