Figure 1. Association of age-related diseases with spirometric results.
Significant parameters from Table 2 are presented in a scatter plot showing the absolute changes in forced vital capacity (FVC) on the X axis and absolute changes in forced expiratory volume in 1 second (FEV1) on the Y axis. The dotted line indicates a slope of 0.775 with a median FEV1/FVC of 77.5%. DM, diabetes mellitus; ESRD, end-stage renal disease. Bars, SD.
