Ventilatory parameters measured at the same relative time during incremental and constant work rate exercise tests as well as the 6MWT (n = 21).

Values are mean (SD).
*p≤0.05 vs. CPET.
Table legend: CPET, Cardiopulmonary exercise test; ISWT, Incremental shuttle walk test; CET, Cycle endurance test; ESWT, Endurance shuttle walk test; 6MWT, Six-minute walk test; VE, Minute ventilation; BF, Breath frequency; VT, Tidal volume; Ti, Inspiratory duration; Ttot, Total breath duration; VE/VCO2, Ventilatory equivalent for carbon dioxide; PETCO2, End-tidal carbon dioxide partial pressure; SpO2, Oxygen saturation by pulse oximetry.

数据以均值±标准差（Standard Deviation, SD）表示。*p≤0.05，与心肺运动试验（Cardiopulmonary Exercise Test, CPET）相比。表格图例：CPET（心肺运动试验，Cardiopulmonary Exercise Test）；ISWT（增量穿梭步行试验，Incremental Shuttle Walk Test）；CET（自行车耐力试验，Cycle Endurance Test）；ESWT（耐力穿梭步行试验，Endurance Shuttle Walk Test）；6MWT（6分钟步行试验，Six-Minute Walk Test）；VE（分钟通气量，Minute Ventilation）；BF（呼吸频率，Breath Frequency）；VT（潮气量，Tidal Volume）；Ti（吸气时间，Inspiratory Duration）；Ttot（总呼吸时程，Total Breath Duration）；VE/VCO2（二氧化碳通气当量，Ventilatory Equivalent for Carbon Dioxide）；PETCO2（呼气末二氧化碳分压，End-Tidal Carbon Dioxide Partial Pressure）；SpO2（脉搏血氧饱和度，Oxygen Saturation by Pulse Oximetry）。
