1

Sensitivity

a/(a+c) = TP/(TP+FN)

2

Specificity

d/(b+d) = TN/(TN+FP)

3

PPV

a/(a+b) = TP/(TP+FP)

4

NPV

d/(c+d) = TN/(TN+FN)

5

which statistical values are affected by prevalence?

PPV and NPV

6

Positive Likelihood Ratio

sensitivity/1-specificity = TP/FP

7

Negative Likelihood Ratio

1-sensitivity/specificity = FN/TN

8

absolute risk

incidence

9

attributable risk

incidence of risk exposed - incidence of risk unexposed

10

Relative risk

Incidence in exposed / incidence unexposed (a ratio) = [a/(a+b)] / [c/(c+d)]

11

Odds ratio

ad / bc

12

Type 1 error

conclude there is a difference when in fact there is not

13

Type 2 error

conclude there is no difference when in fact there is

14

Power

Power = 1 - type 2 error

15

MMR, sabin polio, yellow fever, nasal flu

16

inactivated vaccines (5)

cholera, influenza, HAV, salk polio, rabies

17

Subunit vaccines (5)

HPV, HBV, pneumococcus, meningococcus, pertussis

18

Conjugated vaccines (2)

Hib, S pneumo
