Misinterpretation of the P-value 

P-value - Probability for a given statistical model under the null hypothesis
P-value - Probability ... for a given statistical ... equality of 2 statistical ... not measure the probability ... lower the pretest probability
Specificity Calculation - Probability that a test correctly identifies those without the disease (true negative rate)

Likelihood Ratios - Probability
Remember 2/5/10 and 15/30/45:
 • LR of 2 increases the probability by 15%
Likelihood Ratios - Probability ... increases the probability ... increases the probability ... of 10 increases probability ... decreases the probability
Heparin Induced Thrombocytopenia (HIT) - 4T Score

The 4T score is useful to establish pre-test probability of
establish pre-test probability ... 3 points: Low probability ... : Intermediate probability ... 8 points: High probability
Draw a connecting your pre-test probability and your likelihood ratio. This provides you with your post-test
your pre-test probability ... your post-test probability
