We wish to make the following corrections to our article in the June 2016 issue of Contraception [1]. Page 498, first sentence of the Abstract should read: To compare rates of unintended pregnancy, method continuation and reasons for removal among women using the 52-mg levonorgestrel (daily release 20 microg) intrauterine device (LNG-IUD) or the copper T 380 A IUD (TCu380A). Page 500, left column, first paragraph, first sentence should read: The trial was initially planned for at least 10 years of follow-up of use of the IUDs. Page 504, right column, third paragraph, third sentence should read: The rate of discontinuation due to increased bleeding is slightly higher for the LNG-IUD than for the TCu380A in Chinese centres, while in non-Chinese centres, this pattern is reversed.
