Framework technique used for data analysis

1. Familiarisation	Manuscripts are read and re-read independently by investigators.
2. Identifying thematic framework	Themes are identified and then reviewed jointly and a refined/condensed set of themes agreed on.
3. Coding/indexing	Codes are applied to the data systematically by both investigators independently. Coding is then reviewed and discussed until final consensus on coding is reached.
4. Charting	Data is rearranged in line with thematic content in a manner that supports cross-case and within-case analysis.
5. Mapping and interpretation	Data is interpreted and conclusions and recommendations drawn.
