All statistical analysis and summary graphical representations were performed on Graph Pad Prism® 5.0.
Data extracted included the author, year, methodological approach, sample, location, quality assessment, measures, statistical analysis, and summary of main findings.
For a consolidated statistical analysis, a summary score ranging from 0 to 4 was created by adding up the values of the two 3-point scaled MSD items (with scores of 0 'No, not at all', 1 'Yes, a little' and 2 'Yes, serious').
This section is intended to describe the general approach to the statistical analysis of the summary data that were collected.
Summary statistical analysis was completed for categorical and non-categorical variables.
As this review sought both qualitative and quantitative research, a summary statistical analysis was not performed.
Summary statistical analysis was done using the software program SPSS (Version 21, IBM/SPSS, Inc).
Statistical analysis focused on the summary and detailed description of the data.
The statistical analysis was based on summary data as provided in the source publications: either the number of true and false positive or negative test results compared to the reference test, or the Sensitivity (Se) and Specificity (Sp) of the index tests and 95% CI or credible intervals obtained from latent class analysis.
Statistical analysis was performed using the summary statistic approach to mixed effect modeling.
Matlab 2014 and Excel 2007 were used for the processing of the data and the generation of table summaries, including statistical analysis, respectively.
