Figure 1 - Carbon monoxide diffusing capacity (DLCOSB) as a function of age (upper panel) and height (lower panel) in 100 healthy sedentary subjects. Regression lines are presented with the corresponding 95% confidence limits (CL).
Males: y = -0.15 (age) + 41.4 (CL for x = 12.3) or 0.38 (height) - 30.9 (CL = 12.4), P<0.05.
Females: y = -0.09 (age) + 29.1 (CL for x = 4.8) or 0.23 (height) - 12.4 (CL = 5.2), P<0.01.
Rsq is the coefficient of determination.
