In addition, when the shown, the ladies undergone pelvic test and you may cervical cytological testing. Subsequently, the women obtained ideas on up-to-big date evidence-created and you may direct information regarding per contraceptive approach, the functionality, risk of ill-effects and information adherence. After that, the ladies picked their contraceptive method, that was available with the household believe facility.
From the registration, all women done self-applied surveys about their demographic analysis. New article writers reviewed the fresh ladies upcoming pregnancy plan because of the asking the fresh concern, “Are you willing to plan to has actually children/ anymore students some go out?” The provided solutions was “Yes, I will”, “Zero, I won’t”, and you can “I am not sure”.

Variable age try categorized towards adolescent and you will low-teenage communities to look at the effect of being adolescents into the contraceptive discontinuation a dozen . To check on the newest proportional hazards assumption, we plotted this new diary–log transformation of success setting having birth control style of modified to have other words about last multivariable model contrary to the record analysis go out.
