结局指标

主要结局

VO₂ peak correlation, as measured by Pearson or Spearman correlation coefficient between Calibre and COSMED

时间窗: During CPET testing across Visit 1 and Visit 2, up to 7 days.

VO₂ peak measured during CPET will be compared between devices using Pearson or Spearman correlation coefficient, depending on data distribution.

VO₂ peak agreement, as measured by Bland-Altman bias and limits of agreement between Calibre and COSMED

时间窗: During CPET testing across Visit 1 and Visit 2, up to 7 days.

VO₂ peak measured during CPET will be compared between devices using Bland-Altman analysis to estimate average bias and limits of agreement.

Anaerobic threshold correlation, as measured by Pearson or Spearman correlation coefficient between Calibre and COSMED

时间窗: During CPET testing across Visit 1 and Visit 2, up to 7 days

Anaerobic threshold measured during CPET will be compared between devices using Pearson or Spearman correlation coefficient, depending on data distribution.

Anaerobic threshold agreement, as measured by Bland-Altman bias and limits of agreement between Calibre and COSMED

时间窗: During CPET testing across Visit 1 and Visit 2, up to 7 days

Anaerobic threshold measured during CPET will be compared between devices using Bland-Altman analysis to estimate average bias and limits of agreement.

VE/VCO₂ correlation, as measured by Pearson or Spearman correlation coefficient between Calibre and COSMED

时间窗: During CPET testing across Visit 1 and Visit 2, up to 7 days

Ventilatory equivalent for carbon dioxide (VE/VCO₂) measured during CPET will be compared between devices using Pearson or Spearman correlation coefficient, depending on data distribution.

VE/VCO₂ agreement, as measured by Bland-Altman bias and limits of agreement between Calibre and COSMED

时间窗: During CPET testing across Visit 1 and Visit 2, up to 7 days
