Figure 2. Joint associations between rs35331017 in the PTPRD gene and maternal perceived stress on sPTB in African-American mothers from the BBC.

Figure 2.

Y axis reflects the odds ratio (OR) and 95% confidence interval (CI) of sPTB risk for each subgroup stratified by the genotype of rs35331017 and maternal lifetime stress (Fig. 2A) or stress during pregnancy (Fig. 2B), with low-stress mothers carrying the rs35331017-II genotype as the reference group. This analysis was conducted based on multiple logistic regression models adjusted for genotyping batch, maternal genetic ancestry, age at delivery, marital status, parity, social support from the baby’s father and newborn sex. # 0.05<P < 0.10; ** P < 0.01; *** P < 0.001, **** P < 0.0001.
