Figure 1.

Scatterplots of various important measures. Individual patients have multiple values shown over time, connected with a solid line. A) Plot of WFS patients age versus pre-void bladder volumes. Expected capacity (as a function of age) is shown in gray for comparison. Mean across the whole population is shown as solid line and increases slightly over time as expected. B) Post-void residual bladder volumes. C) Functional bladder capacity for all patients, categorized as either decreased (< 66% estimated bladder capacity), normal, or increased (> 133% estimated bladder capacity).
