Predicted mean of highest 10-second average of VO2 in the last minute of exercise (peak VO2), VO2 at lactate threshold (V02@AT), maximum power output and oxygen pulse depending on irisin levels calculated by linear regression analyses for men (blue) and women (red). Models were adjusted for 1) age, body-mass index, smoking, glucose, total cholesterol levels as well as time between core examination and pulmonary function testing and months of core examination. *The whole population (solid lines) as well as only subjects with a maximal time-lag between blood sampling and pulmonary function testing of one month (dashed lines).
