Data was extracted from reports independently based on the following variables: (a) socio-demographic, and (b) clinical history.
Study results were combined using the DerSimmonian and Laird random effects method of meta-analysis. Between studies heterogeneity was tested using Cochran's Q method. A sensitivity analysis was performed including only the strongest designs, to determine whether the magnitude and significance of risk factors was dependant on including results from studies smaller in design. In the end twenty-nine case studies were identified that met the review criteria.
