One reviewer screened the titles and abstracts of all records for relevance, and assessed potentially relevant records for inclusion.
BRHP data are managed in a dBase system, which was used to extract the relevant records for this period.
The flowchart below, adapted from the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) statement [ 25], illustrates the progressive screening and inclusion of relevant records for the review.
Medical records for mental health of children and young people proved difficult to access and, for some diagnoses, hospitals did not have the required number of relevant records for review.>> -wrap-foot> ataematuria at Haukeland: the two codes used did not identify the cases and the result was discarded.
Sensitivity % is calculated using the following formula: Number of included records retrieved Total number of included records × 100 Sensitivity indicates the ability of the strategy to retrieve relevant records and, for a systematic review, a high level of sensitivity is required to ensure as few potentially relevant records as possible are missed.
For a value of 35, Alice sends Carol three tuples each containing a hash digest of the relevant record key plus hash digests for the numbers 34, 35 and 36.
Bob sends Carol a single tuple for each value for the equivalent attribute in his data collection, containing the hash digest of the relevant record key plus the hash digest for the relevant number – say 36.
Full-text articles of potentially relevant records were assessed for eligibility by two independent reviewers (LB and JvU).
When we excluded one term from the string, the percentage of records missed out of the total number of relevant records averaged 18.7% for omitting "h1n1," 13.6% for "swine," 17.5% for "influenza," and 20.6% for "flu".
A two-layered approach was then used for all relevant records – 39 UK records were marked for prioritization with a further 416 non-UK studies being kept in a holding file.
