Case examples

Example 1: 80 year old male with 8 years of education and an observed mTICS score of 38

mTICS Total predicted = 41.36 − (age*0.15) + (educ*0.29) + (gender*1.29)

mTICS Total predicted = 41.36 − (80*0.15) + (8*0.29) + (1*1.29) = 32.97

mTICS Total z-score = (observed − predicted) / SEE

mTICS Total z-score = (38 − 32.97) / 3.61 = +1.39

Example 2: 50 year old female with 18 years of education and an observed mTICS score of 36

mTICS Total predicted = 41.36 − (age*0.15) + (educ*0.29) + (gender*1.29)

mTICS Total predicted = 41.36 − (50*0.15) + (18*0.29) + (2*1.29) = 41.66

mTICS Total z-score = (observed − predicted) / SEE

mTICS Total z-score = (36 − 41.66) / 3.61 = −1.57

Note. age = years old; educ = years of education; gender: 1 = male, 2 = female; mTICS = modified Telephone Interview of Cognitive Status; SEE = Standard Error of the Estimate of the regression model.
