Neurologic disorders include conditions such as seizure disorders, cerebral palsy, and cognitive dysfunction. Neuromuscular disorders include conditions such as multiple sclerosis and muscular dystrophy. Obesity was assigned if indicated in a patient's medical chart of if BMI was >30.

Renal diseases include conditions such as acute or chronic renal failure, nephrotic syndrome, glomerulonephritis, and impaired creatinine clearance. No known condition indicates that the case patient did not have any known underlying medical condition indicated in the medical chart at the time of hospitalization.
