Sleep quality across gestation and childhood experiences. High ACEs predict poorer sleep quality in relation to lower ACEs. High BCEs predict better sleep quality in relation to lower BCEs. Data were analyzed continuously; for visualization purposes, Fig. 2 displays predicted data based on beta coefficients, mean, and standard deviation of ACEs or BCEs. Average ACEs and BCEs = means of sample, high and low ACEs and BCEs = ± 1 SD respectively. Approximate values: high ACEs = 4, average ACEs = 2, low ACEs = 0; high BCEs = 10, average BCEs = 9, low BCEs = 7
