Measure Type Secondary
Measure Title Changes in Functional Performance in Daily Activities
Measure Description Pediatric Evaluation of Disability Inventory (PEDI) for assessing functional performance in daily activities in children (All values are adjusted and higher value means better functional performance, 0 - worst, 100 - best). We reported here 2 scales and 3 domains of each scale: a Functional Skill Scale (FSS) and a Caregiver Assistance Scale (CAS) which are divided respectively into 3 domains: self care, mobility, and social function. Categories of outcome table are each domain scores measured at each assessment time point.

Measure Title Changes in Hand Function
Measure Description QUEST (Quality of Upper Extremity Skills Test) as a standardized measurement tool for assessing hand function consisting of sub-scales; dissociated movement, grasps, weight bearing, and protective extension. These are standardized to range from zero (or below zero in grasp section) to 100 and higher values mean better hand function. We reported QUEST differences between each assessment times.

[1] Additional details about the analysis, such as null hypothesis and power calculation:
  In our analysis, the null hypothesis is that the effects of 3 experimental groups are same, and the alternative hypothesis is that the therapeutic effect of combination intervention Group (Umbilical Cord Blood + Erythropoietin + Rehabilitation) is higher than that of either Erythropoietin + Rehabilitation or Rehabilitation Group. This is a pilot study and power calculation was not applicable. The sample size of each group is over 30 and is considered to follow approximately normal distribution.
