The associations between red cell distribution width and lung function measures in a general population
BACKGROUND: Red cell distribution width (RDW) reflects heterogeneity of the erythrocyte volumes. High RDW is a novel risk marker, which has been associated with mortality and morbidity both from cardiovascular and respiratory diseases, but the association between RDW and measures of lung function in the general population remains unclear.METHODS: The associations of RDW with spirometry, diffusing
