HLA & disease

Immunology The association of HLA haplotypes with specific diseases is determined by calculating
1. Relative risk Patients with a particular HLA antigen X, Number of control subjects without the antigen, divided by Pts without the antigen X, Control subjects with the antigen–but not the disease and.
2. Absolute risk Patients with the HLA antigen divided by the control subjects with the antigen X
