Equivalence between BMI, ergonomic and exercise interventions in terms of their impact on YLDs. Each pair of points represents a specific number of YLDs averted (in thousands). Values on the y-axis show the percent reduction in occupational risk in workers and the percent of eligible subjects participating in exercise that are required to achieve the same reduction in YLDs as the corresponding reduction in BMI shown on the x-axis. BMI: body mass index; YLDs: years lived with disability
