From: Association of HLA class I with severe acute respiratory syndrome coronavirus infection

  5 deceased or intubated probable SARS patients (Severe cases) 28 Excluded fever patients Control A
101 high risk non-infected health care workers
HLA allele Total number of alleles (n = 10) Total number of alleles (n = 56) OR CI P Pc-value (20) Total number of alleles (n = 202) OR CI P Pc-value (33)
B* 4601 6 9 7.83 1.83–33.47 0.007 n.s. 25 10.62 2.80–40.26 0.0008 0.0279
  1. n= count of alleles; P = P-value; n.s. = not significant. The correction factor (number of different alleles or number of comparisons) is shown within parenthesis; Pc-value = P × Correction factor (Edward, 1974).
