“除非研究结果与哮喘的患病率、严重程度和死亡率的差异有关，否则对哮喘药物治疗差异的研究意义不大。只有部分人群的哮喘死亡率数据，即使可靠，也无法深入了解死亡原因。人们对不同人群之间这种疾病的患病率和严重程度的差异知之甚少。本文描述了哮喘的患病率和死亡率在一些选定的人群，并讨论了可能的原因，观察到的差异，方法获得更多的信息，哮喘的患病率，记录其严重程度和识别那些从死亡的风险。虽然哮喘被定义为可逆的气道狭窄，但患有严重疾病的患者通常会出现不可逆的进行性气道减少，
"Investigation of the differences in the drug treatment of asthma have little meaning unless the results can be related to differences in the prevalence, severity and mortality of the illness. Mortality figures for asthma are available for only some populations and, even if reliable, give little insight into the cause of death. Even less is known about the differences in prevalence and severity of the disease between populations. This article describes the prevalence of asthma and the mortality from asthma in some selected populations and discusses the possible reasons for the observed differences, Methods for obtaining more information about the prevalence of asthma, for documenting its severity and for identifying those at risk from death are suggested. Although asthma is defined as reversible narrowing of the airways, patients with severe disease frequently develop irreversible and progressive reduction in air-
