Prediction equations is forced vital capacity (FVC), forced expiratory volume in 1 second (FEVi), maximum mid-expiratory flow rate (MMFR) and peak expiratory flow rate (PFR) have been derived from a study of 367 asymptomatic Caucasian and Coloured (mixed race) children, aged 11--15 years, who did not smoke. Significant ethnic differences were found in FEVi, FVC, FEVi/FVC, and MMFR/FVC, but not in MMRF or PFR. The practical and epidemiological value of these observations is discussed.
预测方程涉及用力肺活量（FVC）、一秒用力呼气量（FEV₁）、最大呼气中期流速（MMFR）和呼气峰值流速（PFR），这些方程源自对367名11至15岁不吸烟的无症状白种人和混血（混合种族）儿童的研究。在FEV₁、FVC、FEV₁/FVC和MMFR/FVC方面发现了显著的种族差异，但在MMRF或PFR方面未发现差异。本文讨论了这些观察结果的实际和流行病学价值。
