It is a general clinical experience that prognosis varies not only from one disease to another, but also between different categories of patients suffering from the same disease. The object of the study reported was to demonstrate quantitatively how the prognosis of respiratory tuberculosis depends upon the patient's age and sex and upon the severity of disease at the time of diagnosis. Based as it is upon a follow-up through the years 1961-64 of all respiratory tuberculosis patients in Denmark, the study also provides an epidemiological characterization of the course of the disease in northern Europe today.TWO ASPECTS OF PROGNOSIS ARE CONSIDERED: the patients' mortality and their curability. A convenient prognosis index for a group of patients, combining the two aspects, is obtained by expressing the number of patients dying before cure as a percentage of the initial size of the group. The comparison between various patient-categories in the study material is made partly by means of this index and partly by means of annual death and cure rates.
一般临床经验表明，预后不仅因疾病而异，而且在患有同一种疾病的不同类别患者之间也有所不同。本研究报告的目的是定量证明呼吸性结核病的预后如何取决于患者的年龄和性别以及诊断时疾病的严重程度。该研究基于对丹麦所有呼吸性结核病患者在1961年至1964年期间的随访，同时也提供了当今北欧该疾病病程的流行病学特征。研究考虑了预后的两个方面：患者的死亡率和治愈率。通过将治愈前死亡的患者数量表示为该组初始规模的百分比，可得出一个方便的综合这两个方面的患者群体预后指数。研究材料中不同患者类别的比较部分通过该指数进行，部分通过年度死亡率和治愈率进行。
