Resting local and systemic IL-15 relationships

	SkM iIL-15 vs. Plasma IL-15	SCAT iIL-15 vs. Plasma IL-15
All	r = −0.33, P = 0.17, n = 19	r = 0.03, P = 0.92, n = 20
Lean	r = −0.42, P = 0.23, n = 10	r = −0.07, P = 0.85, n = 10
Obese	r = −0.30, P = 0.44, n = 9	r = −0.08, P = 0.84, n = 10

SkM, skeletal muscle; SCAT, subcutaneous adipose tissue; iIL-15, interstitial IL-15. Resting relationships between local (SkM and SCAT) interstitial sources of IL-15 (iIL-15) and circulating IL-15. As indicated, there are no significant relationships (P ≥ 0.17 for all analyses) between local and systemic IL-15.
