Association between geographic proximity and prenatal depression using restricted cubic spline regression. The associations are presented as risk ratios (ORs, solid line) and the 95% CIs (dashed line) using logistic regression after adjusting for age, pre-pregnancy BMI, gestational weeks and place of household registration. The value of geographic proximity to COVID cases at 8 km was chosen as reference. Knots were placed at the 5th, 50th, and 95th percentiles of geographic proximity. CI, confidence interval
