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

Likelihood Ratios - Probability
Remember 2/5/10 and 15/30/45:
 • LR of 2 increases the probability by 15%
