Figure 1.

Distribution of CGM-measured glucose levels throughout uncomplicated pregnancies. Envelope plots of the per cent of CGM values within each glucose level interval for each participant during (A) the entire observed gestational period (N=413) and (C) each trimester (N=118, 413, and 355 in the first, second, and third trimester, respectively). Tracings of participant-level mean glucose levels by the hour of the day during (B) the entire observed gestational period and (D) each trimester. Solid dots and lines represent medians, and open circles represent means. Shaded bands represent the IQR (ie, 25th–75th percentiles). The first, second, and third trimesters are represented by the colors blue, red, and green, respectively. CGM, continuous glucose monitoring.
