Association of Irisin with Fat Mass, Resting Energy Expenditure, and Daily Activity in Conditions of Extreme Body Mass Index

Figure 3

Daily physical activity and resting energy expenditure and its correlation with irisin. The average daily physical activity (units/day) and resting energy expenditure (REE: kcal/day) for the AN, NW, and OB subjects are shown in (a) and (b), respectively. Asterisk (^∗𝑃<0.05 and ^∗∗∗𝑃<0.001) denotes statistically significant differences between normal weight and anorexia nervosa or obesity versus anorexia nervosa and normal weight. The correlations between the circulating irisin and the daily physical activity and REE for the three groups are presented in (c) and (d).
