It is associated with the development of berry aneurysms, which may cause mechanical compression of the nearby CN III in the event of development of posterior communicating artery aneurysm. +
71% represents the positive predictive value (PPV) of the test. PPV is calculated using the following equation: PPV = TP/ (TP+FP). 80% represents the negative predictive value (NPV) of the test. NPV is calculated using the following equation: NPV = TN/ (TN+FN) +
Vitamin B12 is a cofactor for homocysteine methyltransferase and methylmalonyl-CoA mutase. +
The patient's pericarditis is caused by the patient's recent upper respiratory infection. However, the patient's past medical history is not associated with the severity of his presentation. +

Cardiac arrhythmias are common post-MI complications, but the patient's signs and symptoms are not suggestive of cardiac arrhythmias. +
α (type 1 error) represents the likelihood of obtaining a significant difference when there actually is none. The p-value represents the α or type 1 error of a study. As a rule, for the same population size, as α decreases (p-value cut-off becomes more stringent), β increases. As power = (1-β), higher β values lower the power of a study. Therefore decreasing the p-value cut-off to <0.01 will decrease the statistical power of the study. +
Locus heterogeneity is defined as mutations at different locations that result in the same phenotype. +
QRS complexes represent ventricular depolarization and simultaneous atrial repolarization. +
The onset of symptoms correlates with AS severity and is an indication for surgical intervention. +
