JCVO, MHSG and RPV performed data analysis and categorization.
The first two authors participated in data analysis and categorization; the first author coded data, which was re-checked and discussed by members of the study team.
In line with the advice in Yin's book on case study research [ 18] our data analysis consisted of examination, categorization and tabulation of the evidence as well as use of the dominant analytical technique, pattern-matching.
The remaining authors participated in assisting with the development of the categorization schemes and data analysis.
The enrichment categorization implemented in the data analysis pipeline is based on previous studies [ 49, 55– 60] and provides a full complement of graphic outputs.
PT conducted the systematic literature review, selection and categorization of cases, data extraction, data analysis, writing of the manuscript, and is guarantor.
Data analysis followed a constant comparative method for qualitative data categorization and analysis [ 35].
As Hoshmand (1989) indicates, data analysis in qualitative research involves a cyclical descriptive process of categorization, coding, and recoding of data with the aim of achieving an internal order by identifying themes, categories, and subcategories.
We used qualitative data analysis software (NVivo, version 7) to assist in the organization and categorization of data.
Qualitative data analysis software (Open Code Version 3.5) was employed to identify the key issues from these interviews through coding, categorization and grouping into emergent themes.
participated in data analysis.
