Percentile curves for evaluation of repeated measures of lung function.
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.
