Core Tip

Core Tip: This study was performed to assess whether restrictive and obstructive patterns of pulmonary disease and type 2 diabetes mellitus (T2DM) are associated with each other in Koreans. For our analysis, we used data from the Korea National Health and Nutrition Examination Survey. A total of 2830 subjects were included in this study. Spirometry results were categorized into three patterns: normal, restrictive, and obstructive pulmonary disease. Restrictive pulmonary disease, not obstructive disease, is highly relevant to T2DM regardless of other risk factors of various T2DMs that can be confounds.
