The relationship between peak expiratory flow rate scores recorded with the standard Wright meter and those recorded with the mini-Wright meter was determined by correlating these scores on an intraindividual basis. These correlations were compared with correlations between pairs of standard scores. The latter were computed so as to provide an estimate of peak expiratory flow rate variability unrelated to recording apparatus. The results showed that pairs of standard Wright scores were more highly related to one another than were pairs of standard and mini-Wright scores. From these observations it was concluded that standard and mini-Wright scores are not equivalent and therefore may not confidently be interchanged.
通过在个体内对标准赖特流量计和微型赖特流量计记录的呼气峰值流速分数进行相关性分析，确定了两者之间的关系。将这些相关性与标准分数对之间的相关性进行比较。计算后者是为了估计与记录设备无关的呼气峰值流速变异性。结果表明，标准赖特分数对比标准与微型赖特分数对之间的相关性更高。从这些观察结果得出结论，标准和微型赖特分数并不等同，因此不能放心地相互替换。
