A statistically significant, after correction of P value, increased incidence of the antigen HLA-DR4 chi 2 = 32.81, p less than 0.001, was established in the comparison of the antigen incidence of HLA-A, B, C and DR antigens in 59 patients with classical and positive rheumatoid arthritis and control healthy subjects. No essential difference in the distribution of DR4 was established that depended on sex, age of occurrence of the disease, presence of rheumatoid factor and the form of the disease.
在对59例典型和阳性类风湿性关节炎患者以及对照健康受试者的HLA - A、B、C和DR抗原的抗原发生率进行比较时，校正P值后发现，抗原HLA - DR4的发生率有统计学显著性增加（χ2 = 32.81，p < 0.001）。未发现DR4的分布在性别、发病年龄、类风湿因子的存在以及疾病形式方面存在本质差异。
