STATA Corporation xtlogit command
Fresh-CT, fresh cleavage stage embryo transfer; NC, natural conception; fresh-BT, fresh blastocyst transfer; frozen-CT, frozen cleavage stage embryo transfer; frozen-BT, frozen blastocyst transfer. Adjusted for year of delivery (categorical: 1988–1996, 1997–2001, 2002–2006, 2007–2011, 2012–2015), maternal age (categorical: 20–24, 25–29, 30–34, 35–39, 40–45), parity (categorical: 0, 1, 2, 3), and country (only included in analyses at the population level because it is constant within mothers). Analyses in “Smoking” are additionally adjusted for smoking status in the subpopulation where this information was available. In “C-section” the outcome of placenta previa is restricted to pregnancies delivered by cesarean section, whereas “Full siblings,” “First two,” “<3 years,” “SET,” “IVF,” and “Singletons” refer to restriction of analyses to full siblings (i.e., same mother and father), each mothers’ first 2 consecutive <t>deliveries,</t> only consecutive deliveries less than 3 years apart, single embryo transfer (using all deliveries after NC as reference), in vitro fertilization (using all deliveries after NC as reference), and singleton pregnancies, respectively.
