Notes: (A) The nutrient supplementation at optimal physiological level may improve lung function that in turn offsets the age-related decline over time. In this pattern, the onset of the intervention improves the lung function without affecting the decline slope. (B) The intervention could directly slow down the age-related lung function decline as reflected by a less steep slope.
