Literature Search Filters for Neonatal Reviews

Literature Search Filters for Neonatal Reviews

Filters

Below find filters to restrict retrieval to:

·       Neonatal populations

·       Randomized controlled trials (RCT)

·       Systematic reviews (SR).

The most strongly recommended filter is that for the population. We recognize the filter is sensitive, but it is a best effort to capture relevant studies.

Feel free to use different RCT and SR filters, but please provide source information, e.g. ad hoc filters are not encouraged; nor are database “limits” as found in some search interfaces.

 

Neonatal Population Terms/Filters:

These terms are used to restrict retrieval to neonatal populations. The terms are sensitive and will find unrelated populations, but we recommend its use given that a lack of sensitivity could mean relevant or potentially relevant studies are missed.
