Table 3. DLCO, DL_COc, K_CO values and scintigraphic index in patients with syndrome X and control subjects.

DL_CO: Diffusing capacity of the lung for carbon monoxide, DL_COc: Corrected diffusing capacity of the lung for carbon monoxide, K_CO: Transfer coefficient, PI: Penetration index, CR: ^99mTc-DTPA clearance rate (t ½ values), NS: Non-significant. *: Values are expressed as percent predicted. Values are expressed as mean±SE.
