Mean change 0.55 0.45 0.27 0.291  
St. error change 0.28 0.23 0.26 0.10 3.76
P-Value 0.0690 0.0690 0.3000 0.0100  
Robot-assisted therapy (n = 8)      
Admission 2.00 2.63 5.25 2.53 75.80
Discharge 3.50 3.88 5.75 2.96  
Mean change 1.50 1.25 0.50 0.481  
St. error change 0.33 0.27 0.30 0.12 4.41
P-value 0.0003 0.0003 0.1130 0.0010  
Difference in treatments 0.95 0.80 0.23 0.201 5.39
Standard error Difference 0.43 0.36 0.39 0.15 5.79
P-value 0.0410 0.0410 0.5710 0.2240 0.3650
  1. 1 For ln(CAHAI-7), admission and discharge are the means of the natural log values. However, the mean change and difference in treatments (and their standard errors) are adjusted for age differences of subjects.
