Figure 4. — Cumulative incidence of PE comparing the first decile of the cortisol-to-cortisone ratio with the second through 10th deciles of cortisol-to-cortisone ratio from (A) 28 wkGA onward in cases of preterm PE and (B) 36 wkGA onward in cases of term PE. (A) Reported in births per 1000 women; (B) reported in births per 100 women. Cases of PE were defined by the ACOG 2013 Guidelines (25) and included all severe and nonsevere, nonsuperimposed PE at term and all preterm PE. Preterm delivery included pregnancies delivered <37 wkGA, and term delivery included pregnancies delivered ≥37 wkGA. Delivery without PE was considered as competing risk. PTD, preterm delivery; SHR, subhazard ratio.
