Search strategies used for the cirrhosis guideline are outlined below and were run in accordance with the methodology in the NICE guidelines manual 2012.92 All searches were run up to 24 th August 2015 unless stated otherwise. Any studies added to the databases after this date (even those published prior to this date) were not included unless specifically stated in the text. We do not routinely search for electronic, ahead of print or ‘online early’ publications. Where possible searches were limited to retrieve material published in English.
Database date parameters.
Searches for the clinical reviews were run in Medline (OVID) and Embase (OVID) except the risk tools question (G.4.2) which was run in Medline only. Additional searches were run in the Cochrane Library, see .
Searches for intervention and diagnostic studies were usually constructed using a PICO format where population (P) terms were combined with Intervention (I) and sometimes Comparison (C) terms. An intervention can be a drug, a procedure or a diagnostic test. Outcomes (O) are rarely used in search strategies for interventions. Search filters were also added to the search where appropriate.
Searches for prognostic studies were usually constructed combining population terms with prognostic variable terms and sometimes outcomes. Search filters were added to the search where appropriate.
Searches for the health economic reviews were run in Medline (OVID), Embase (OVID), the NHS Economic Evaluations Database (NHS EED), the Health Technology Assessment (HTA) database and the Health Economic Evaluation Database (HEED). NHS EED and HTA databases were hosted by the Centre for Research and Dissemination (CRD). The Health Economic Evaluation Database (HEED) ceased production in 2014 with access ceasing in January 2015. For the final dates of HEED searches, please see individual economic questions.
For Medline and Embase an economic filter (instead of a study type filter) was added to the same clinical search strategy. Searches in CRD and HEED were constructed using population terms only.
G.2. Population search strategies
G.2.1. Standard cirrhosis population
The standard population was not used in questions G.4.2, G.4.5, G.4.7, G.4.9, G.4.10, G.4.11, G.5.2 and G.5.2.

Which risk assessment tool is the most accurate and cost-effective for predicting the risk of morbidity and mortality in people with compensated cirrhosis?
When (at what severity score on the risk assessment tool) should people with cirrhosis be referred to specialist care?
