Comparisons are made between the principal diagnosis on discharge from hospital in successive periods of inpatient care for persons in the Oxford Record Linkage Study area admitted over a period of years. The observed numbers of pairs of diagnoses are compared with expected numbers computed to take account of the discharge rates in the population by age and sex and the number of man years of exposure. Three topics have been selected to display some of the types of analysis possible with the very extensive material: mental disorder and diseases of the central nervous system, hospital discharges preceding those for neoplasm, and discharges following those for tuberculosis. The details of the method of calculation of the observed and expected numbers and the assumptions and approximations involved are given in an Appendix.
对牛津记录链接研究区域内多年来住院治疗的患者在连续住院期间的出院主要诊断进行了比较。将观察到的诊断对数量与考虑到按年龄和性别划分的人群出院率以及暴露人年数计算出的预期数量进行比较。选择了三个主题来展示利用这些非常广泛的材料可能进行的一些分析类型：精神障碍和中枢神经系统疾病、肿瘤诊断之前的出院情况以及结核病诊断之后的出院情况。观察值和预期值的计算方法细节以及所涉及的假设和近似值在附录中给出。
