Mean levels of inflammatory markers in twins with and without the metabolic syndrome (MetS).

Presence of MetS
Inflammatory markers No Yes %
Difference		 P Value
(Unadjusted)		 P Value
(Adjusted)*
CRP (mg/L)† 1.62 3.07 89.5 < 0.0001 < 0.0001
IL-6 (pg/mL) 2.05 2.62 27.8 0.0003 0.0005
TNF-a (pg/mL) 1.45 1.58 9.0 0.096 0.063
sIL-6R (pg/mL) 28.6 29.9 4.5 0.398 0.438
sTNF-RII (pg/mL) 1.98 2.15 8.6 0.013 0.029

CRP = C reactive protein; IL-6 = interleukin-6; TNF-a = tumor necrosis factor alpha; sIL-6R = soluble IL-6 receptor; sTNF-RII = soluble TNF receptor

MetS: Metabolic Syndrome

*

Adjusted for age, education and current smoking. P values were corrected for pair cluster using GEE regression.

†

Data were missing for 2 twins with MetS and in 2 twins without MetS
