Smoothed glucose curves and results from the multilevel FPCA.

<p>Plots A and B show individually smoothed curves from gestational weeks 14–16 and 30–32 (black lines) and the visit-specific mean curves (grey lines). Plots C and D show the overall mean of the fitted curves (grey lines) and how the shape of an individual curve differs from the overall mean if a multiplum of the subject-specific FPC curves is added to (+) or subtracted from (−) the mean curve. Plots E–G and H–J show the visit-specific means at gestational weeks 14–16 and 30–32, respectively (grey lines), and how the shape of an individual curve differs from the visit-specific mean if a multiplum of the subject- and visit-specific FPC curves is added to (+) or subtracted from (−) this mean. The multiplums correspond to 2 SDs of the corresponding FPC scores.
