Abstract
OBJECTIVE\nSTUDY DESIGN\nRESULTS\nCONCLUSIONS\nIMPLICATIONS\nTo compare plasma etonogestrel concentrations sampled from the contralateral- versus ipsilateral-to-implant arm.\nSub-analysis of a cross-sectional study in Botswana in 33 participants who provided contralateral and ipsilateral blood samples.\nPlasma etonogestrel concentrations in contralateral and ipsilateral specimens were highly correlated (correlation coefficient = 0.99; p < 0.0001). Bland-Altman analysis of agreement showed that etonogestrel levels were on average 5.9 pg/mL higher (2.1%) in ipsilateral compared to contralateral specimens (95% confidence interval: -4.1, 15.9 pg/mL).\nWe found no meaningful differences in plasma etonogestrel concentrations between samples taken from the contralateral- versus ipsilateral-to-implant arm.\nOur data suggest that etonogestrel plasma concentrations are unlikely to be meaningfully different between samples drawn from the ipsilateral- versus the contralateral-to-implant arms in etonogestrel contraceptive implant users.
