Strengths and limitations
UTIs
A strength of this study is the range of participants interviewed, particularly across the age groups. The authors found qualitative interviews a very useful method for collecting data about a highly personal issue such as UTIs, and the women felt able to speak with candour and in detail about their experiences.The women interviewed in this study had participated in an RCT because they were positive about trying out a UCD. This might not be the case among a wider general practice population.
