  • *

    * Similar results in analyses adjusted for age and sex; no statistically significant effect modification by sex in the associations of either MetS definition with risk of being in the lowest quartile of Si, AIR, or DI, with the exception of the NCEP definition for DI, which had a significantly stronger association among women.

  • ORs are from separate models and refer to the risk of being in the lowest quartile of Si, AIR, or DI in those with MetS compared with those without MetS (OR = 1 in the latter group).
