An epidemiological survey of 1239 normal subjects without respiratory symptoms was undertaken in an urban locality of New Delhi in 1974. The subjects were divided into males aged under or over 22 and females under or over 17. Various statistical models were calculated to relate peak expiratory flow rate to the age, height, and weight of the subjects in each group. The linear model was simple, convenient, and adequately explained the variation in peak expiratory flow rate.
1974年,在新德里的一个城市地区对1239名无呼吸道症状的正常受试者进行了一项流行病学调查。受试者被分为22岁以下或以上的男性以及17岁以下或以上的女性。计算了各种统计模型,以将呼气峰值流速与每组受试者的年龄、身高和体重联系起来。线性模型简单、方便,并且充分解释了呼气峰值流速的变化。
