1

ICC model 1

each subject tested by different raters.

*raters random
assess difference among subjects

2

ICC model 2

each subject tested by same raters

*raters and subjects random
assess interrater reliability

3

ICC model 3

each subject tested by same rater

*purposely chosen.
used to measure intrarater reliability.

4

measuring change order

MPDD -> MDD (smallest change that can be interpreted as any inprov. or decline.) -> MCID (meaningful change)

5

Sensitivity

probability of getting a true positive.

a/(a+c)

1-this = false negative rate

6

specificity

probability of getting a true negative.

d/(b+d)

1-this = false positive rate

7

SpPin

high specificity, positive test, rule in

8

SnNout

high sensitivity, negative test, rule out

9

positive likelihood ratio

odds of a disease are increased if a test is positive

true positive rate/false positive rate
sensitivity/ (1- specificity)

10

negative likelihood ratio

odds of a disease are decreased if test is negative

false negative/ true negative
(1-sensitivity) / specificity
