Data on views of diabetes care tabulated by theme from a subsample of papers

Reading/re-reading wider sample of papers to explore/develop thematic analysis and similarities/differences across participant groups

Creation of a conceptual map summarising emerging themes

All papers tabulated by study characteristics, quality and data answering the synthesis question (labelled by participant group— children, young people or young adults, parents, clinicians) (see online supplementary appendix 6)

From this, core themes identified for each group, using constant comparison of data within groups to identify patterns of similarity and difference.

Data clustered by group and theme to explore similarities and differences in priorities and experiences across participant groups

Content analysis of numbers of studies, participants in each group and range of aspects of care explored for each

Comparison of findings from the exploration of relationships with findings from the preliminary synthesis

Discussion across the research team to resolve differences
