Figure 2.

Association between eGFR and at (A) least one SMM indicator, (B) preterm birth (gestational age <37 weeks), and (C) low birthweight (weight <2500 g). SMM indicators were measured between 20 weeks of gestation and 42 days after the index delivery. Restricted cubic splines for eGFR were calculated with five percentile knots in a logistic regression model with the binary outcome for SMM, preterm birth, or low birthweight. The figures provide a visual representation of the relationship between the outcomes and eGFR truncated at 100 ml/min per 1.73 m²
