The exact probability of stroke can be determined using the logistic regression formula: probability = 1/[1 + exp –(intercept value + 0.8141*Arterial hypertension + 0.6392*Dyslipidemia + 1.6108*Atrial fibrillation + 1.1722*Active smoker + 0.9541*IgA aB2GPI Positive)]. This evidence concerns the gene CD79A and Hypertension.
