We used the first 10 included articles to test the content extraction forms, which were discussed and modified until consensus was reached and the method for data extraction was standardised.
Hip fracture incidence rates for individuals aged ≥ 50 years in Sweden during the period 1987–2002 (Table) have been described in detail previously, together with the method for data extraction from the official Swedish Inpatient Records (Rosengren et al. 2012).
Practice computer databases were interrogated using Morbidity Information Query and Export Syntax (MIQUEST) software which has been validated as an accurate and appropriate method for data extraction of patients with CKD in general practice [ 17].
This review was guided by a written pre-specified protocol describing research questions, review methods, plan for data extraction and synthesis.
Feasibility relates to evidence about whether accurate data are available and collectable in current family practice information systems, and supported by current methods of data extraction for QOF.
Besides, the vast amount of imaging data that are acquired in population-based studies like the Rotterdam Study renders visual assessment or manual measurements virtually impossible, strengthening the need for (fully) automated methods of data extraction and analysis.
The method requires that, for data extraction and synthesis, 'ecological sentences' are formulated following the pattern: 'With this intervention, these outcomes occur with these population foci and within these grades (ages), with these genders... and these ethnicities in these settings' [[ 39], p1].
This method of data extraction was based on the approach used for the World Cancer Research Fund second expert report.
Describe the method of data extraction from reports (such as piloted forms, independently by two reviewers) and any processes for obtaining and confirming data from investigators.
For data extraction, five-step method is used and isochromatics are evaluated by twelve fringe photoelasticity.
For data extraction, normalization and filtration, we used the methods as described in our previous work [19].
