4 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame

Time Frame: 5 years
Pearl Index over 5 years of use of Sino-implant (II) ; continuation & reasons for discontinuation in both groups.
5 years
Compare concentrations of levonorgestrel through 5 years after insertion of Sino-implant (II) and Jadelle
Time Frame: 5 years
annual and cumulative probability of pregnancy during 5 years of use of Sino-implant (II);
5 years
Compare pharmacokinetic profiles of Sino-implant (II) and Jadelle during the first 6 months of use in a sub-group of users undergoing intensive levonorgestrel sampling
Time Frame: 5 years

The PK profile of LNG during the first 6 months post-insertion including the following parameters in a sub-group of users undergoing intensive LNG sampling:

Mean LNG concentrations at 6 hours, 24 hours, 48 hours, 72 hours, 7 days and 90 days post-insertion Concentration-time profiles of LNG (individual and pooled) Maximal concentration (Cmax) and time to maximal concentration (Tmax) AUC0-7 days, AUC0-1mon, AUC0-3mon and AUC0-6mon

5 years
Compare the safety and acceptability of Sino-implant (II) and Jadelle during 5 years of use
Time Frame: 5 years
Adverse event rates in both treatment groups Annual and cumulative probability of early discontinuation in both treatment groups Reasons for discontinuation in both treatment groups Responses on acceptability questionnaires in both treatment groups
5 years
