Mean differences (unadjusted and adjusted) in physical performance by different grades of low FEV₁ compared to reference group (FEV₁ > 0 SD) for the overall cohort and subgroup without AO on spirometry (shown here as FEV₁/FVC > = LLN).

Mean differences (unadjusted and adjusted) in physical performance by different grades of low FEV1 compared to reference group (FEV1 > 0 SD) for the overall cohort and subgroup without AO on spirometry (shown here as FEV1/FVC > = LLN).本数据集呈现了全研究队列，以及肺量计检查中无气道阻塞（AO）且FEV1/FVC≥正常下限（LLN）的亚组中，不同分级的低第一秒用力呼气容积（FEV1）人群与参照组（FEV1＞0标准差）之间的体能表现的未校正与校正平均差异。
