Figure 4From: Sequence variants in oxytocin pathway genes and preterm birth: a candidate gene association study Results of TDT analysis for three OXTR coding SNPs detected in U.S. maternal triads by sequencing. Data on three OXTR SNPs (rs4686302, rs237902, and rs61740241) were analyzed on all GAs or five-week sliding window-stratified subgroups. Note that no data were available for some GA subgroups due to the lack of a sufficient number of informative families.Back to article page
