CD79A and autoimmune polyendocrinopathy: Based in the three-variables model described in the multivariable analysis (Table 4-C), an easy risk-calculator for APS-events, where we predicted probabilities of the APS event for a patient, can be established using the formula p = 100*(1/(1+Exp(-6.478+ [1.658*IgA-aB2GP1 positive]+[0.051*age in years]+ [0.903*sex]))).[25] For each patient, in this formula the value of IgA-aB2GP1 positive is 1 (0 for IgA-aB2GP1 negative) and the value of gender-male was 1 (0 for female).
