Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Implanon | Implanon® (Org 32222) is a single rod contraceptive implant of 4 cm length and 2 mm in diameter. Implanon® contains approximately 68 mg etonogestrel (ENG) (Org 3236, 3-ketodesogestrel) dispersed in a matrix of ethylene vinyl acetate (EVA)copolymer, surrounded by an EVA membrane.~The ENG dose released by Implanon® amounts to about 60-70 μg/day shortly after insertion and decreases to about 40 μg/day at the start of the second year, and to about 25-30 μg/day at the end of the third year. | 6 | 56 | EG000 |
| Group 2 | Radiopaque Implanon | The radiopaque rod (Radiopaque Implanon) is similar to the Implanon rod except for the addition of barium sulfate. | 4 | 52 | EG001 |
