  1. aMean (Standard Deviation) is reported for variables that were normally distributed. Median (Interquartile Range) is reported for variables with a non-normal distribution
  2. bValues for orthostatic shift in blood pressure are presented as lying-standing to examine postural drop. Reference range for heart rate and orthostatic shifts in pulse and blood pressure are based on admission criteria recommended by the Society for Adolescent Medicine [35]
