Scatterplots of pons volumes corrected for whole brain volume on annual MRI correlated to three validated patient-reported outcome measures, including A) Pediatric Incontinence Quality of Life (PinQ), B) Toronto Bowel and Bladder score, and C) Compass-31 questionnaire, which assesses autonomic function. Trendlines correspond to individual patients in each linear mixed-model, adjusted for age and sex (projected using mean values of non-visualized variables). P value for each model is shown.
