We followed participants who had a postplacental TCu380A IUD insertion, at two postpartum visits: 45\u201390\u00a0days (visit 1) and 6\u20139\u00a0months (visit 2).

We observed missing strings in 275 (47.9%) participants at visit 1, and in 127 (34.2%) participants at visit 2. We identified 61 expulsions (8.9%) by visit 2. In the multiple regression models, only the delivery type was associated with missing strings and expulsion. Compared with vaginal delivery, cesarean delivery increased the risk of missing strings (adjusted relative risk [aRR] 6.21; 95% confidence interval [CI] 4.29\u20138.99) but reduced the risk of IUD expulsion (aRR 0.24; 95% CI 0.13\u20130.43).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The delivery mode was the only factor associated with missing strings and expulsion after postplacental IUD insertion.
