Trip (Free-Version)

"Trip’s a leading tool to identify evidence from the global evidence-base. Our guideline coverage is one of the stars ..." (see https://blog.tripdatabase.com/2021/10/21/a-bonanza-of-new-guidelines-added/)

Pro version with: more systematic reviews, ongoing clinical trials, medical images, clinical videos, link to full-text articles, export function (55 $ per year for a single person or institutional license), see https://www.tripdatabase.com/Pro

Special features:

  • Filter by quality, differentiated by colour, i.e. "Secondary Evidence" (Systematic Reviews, Guidelines, ...), green, comes first, see evidence pyramid below.
  • Guideline score since 5/2023, see Info
  • Standard sorting by "Quality", among others by Publication score, i.e. by the quality of a source.
  • "Key primary research" filter (see section "Evidence filter ...")
  • Fewer hits than in PubMed, since, among other things, fewer journals are evaluated (e.g. around 550 journals "Primary research"), therefore more manageable
  • additional content beyond "research evidence", see filter graphic below in yellow area

Search options

  • AND/OR/NOT search with bracketing or Advanced Search (Pro).
  • Wildcard * at the end of words allowed, but automatic singular/plural and synonym search, e.g.: "renal stones" finds "kidney stone", prevention finds prevent and preventing.

  • Phrases in inverted commas ("term term")
    Note: Truncated phrases not allowed (* is ignored, e.g.: "renal ston*" does not find any hits)
  • Date filter in the Advanced Search before the search (From:), or via "Further Refinement" at the bottom left after the search
  • Proximity function in the search field via "term term"~number, or in the Advanced Search (terms max. N words apart, adjustable from 1-10, any order of the terms)
