Subject Subset Limits updated, and new COVID-19 Limit added to Ovid MEDLINE – April 2020


Subject Subset Limits updated, and new COVID-19 Limit added to Ovid MEDLINE

Dear Ovid MEDLINE Customer:

On 14 April 2020 we updated the Dietary Supplements and Toxicology Subject Subsets Limits for Ovid MEDLINE, following the NLM’s changes to their
PubMed Subject Filters:

All NLM PubMed Subject filters are translated into Ovid syntax and match the PubMed results as closely as possible. You can find more information about the Ovid MEDLINE limits in the Ovid MEDLINE database guide:

We have documented the exact translations from PubMed to Ovid search syntax, including the new and legacy limits for Systematic Reviews, under the Ovid Expert Searches area:

In addition, we have now added our COVID-19 Limit for Ovid MEDLINE to the “Special Ovid Filters” area. This new limit allows researchers to easily combine their search strategies with the quickly growing collection of MEDLINE records on the topic of COVID-19. The exact search syntax for this limit is also documented in the Ovid Expert Searches area, and the Ovid MEDLINE database guide:

Here’s an example:

    or tips for new aspiring blog owners. Appreciate it!
