1. Translation: Aufteilung der Suchfrage in einzelne Aspekte, z.B. PICO

2. Operators: Boolesche oder proximity Operators korrekt?

3. Subject headings: fehlen wichtige? Exploded terms, subheadings?

4. Natural language: Textwords: Schreibvarianten, Trunkierung, verwandte Begriffe

5. Spelling & syntax: Tippfehler? Syntaxfehler? Richtige Zeilennummern kombiniert?

6. Search filters: systematic reviews, RCTs, guidelines, etc.?

7. Limits: publication types, methodological filters, language, dates?

8. Fields: title, abstract, etc.?

9. Adapted databases: wurden alle relevanten Datenbanken verwendet? Wurden die Strategien

entsprechend an die Datenbankfunktionen angepasst?

1.1. Wenigste Information:

Search Strategy:

Electronic searches were carried out in PubMed

(NLM) and the Cochrane Library (Wiley). The

searches were performed in November 2015.

All databases were searched up to the latest

issue available or to the update status at the date

of search. There were no language or time period

restrictions.

We used detailed search strategies including

keywords with synonyms and, in databases with

a thesaurus, controlled vocabulary terms .

The individual search algorithms of databases

are available on request.

The search was conducted using a combination

of the following keywords: varices, variceal,

bleeding, hemorrhage, prevention, prophylaxis.

The individual search algorithms of databases

are available on request.

2. Strategie von mindestens 1 Datenbank:

[Datenbanken, Anbieter, Suchdatum und Suchzeitraum identisch mit 1.1.]

The PubMed search strategy (Table 1) was adapted for the other

databases according to their specific search functions and index terms.

Detailed search strategies are available on request.
