Figure 4 - Positive relationship between oxygen uptake at maximum cycle ergometry (VO_{2}max,
ml/min) and the carbon monoxide diffusing capacity (DL_{CO}SB).
The slope of this relationship was similar in both sexes (35.36) but with different
intercepts (979 in males and 455 in females, SEE = 387, P<0.01). The regression line is
presented with the 95% confidence limit (CL). Rsq is the coefficient of determination.
