Mean trajectories of clusters* based on functional curves of phthalates vs. gestational age. *Clusters are constructed based on functional k-means clustering (Functional clustering model) of the smooth curve of residuals (from a regression model of MEHP or MBP on relevant covariates) against gestational age. N=443 for each phthalate model.
