There were no subgroups for behavioural, case management and methodology retention trials.
This is followed by views on other less frequently evaluated strategies identified by the Cochrane review, 2 that is, behavioural, case management and methodological strategies.

If retention strategies found by the Cochrane review 2 (ie, incentives, communication methods, new questionnaire formats, behavioural, case management and methodological strategies) were not mentioned spontaneously by interviewees, they were asked specifically about these (Interview schedule online supplementary appendix 1).
Data on contraception were collected every 4 weeks from enrolment from the following question in the sexual behavioural case record form: 'Are you currently using any form of family planning?' Where available, these data were cross-checked with the contraception dispensing data.
