Modified BODE indexes: Agreement between multidimensional prognostic systems based on oxygen uptake.
It has been recently shown that the original BODE index has a high degree of correlation with two modified BODE indexes using maximal oxygen uptake expressed either as mL/min/kg (mBODE) or as the percentage predicted (mBODE%). In this study we investigated the agreement between the two modified BODE indexes (mBODE and mBODE%) in patients with stable chronic obstructive pulmonary disease (COPD). ⋯ The new mBODE indexes are highly correlated but significantly different from each other. The differences between the novel indexes deserve further scrutiny.
