Bibliographical noteFunding Information:
NVivo Pro (version 11; QSR International, Warrington, UK) computer software was used to manage and support the coding of data. Initial codes were created around the main interview questions and comparison made across the women’s experience on each arm of the trial and health-care professionals’ accounts. The research team members were involved in ongoing discussions as data collection and analysis progressed. The use of computer software helped to facilitate a critical and rigorous approach to the assignment and with the interpretation of the codes and emergent themes.21 A two-cycle approach to coding was undertaken.22 First-cycle coding involved applying structural coding, which facilitated an approach whereby the data were coded according to broad topics [i.e. experience of transvaginal ultrasonography (TVU)]. The segments of data were then subject to further analysis and comparison. Analysis and interpretation were supported by analytic memo writing on emergent patterns and themes. Second-cycle coding further refined the original codes and memos into a smaller number of categories that were subject to further analysis and interpretation. This stage of the analysis involved a team approach, helping to improve the rigour of the findings.23
