Methods are discussed for evaluating repeated measures of an individual's lung function over time, based on the concept that the best estimate of a subject's lung function at any time is a previous measurement of his or her lung function. Rather than considering change in lung function measurements over time, individuals are evaluated based on the degree that their lung function tracks along fixed percentiles within a reference population. Measures of FVC and FEV1 are focused upon.
基于这样一种概念，即个体在任何时候的肺功能的最佳估计值是其之前的肺功能测量值，本文讨论了评估个体随时间变化的肺功能重复测量值的方法。不是考虑肺功能测量值随时间的变化，而是根据个体肺功能在参考人群中沿着固定百分位数的跟踪程度来评估个体。重点关注用力肺活量（FVC）和第一秒用力呼气容积（FEV1）的测量值。
