  • Model A included all variables that showed significant differences between women with and without low grip strength in table 1. Model B included all variables in model A, except for adiponectin, as independent variables. In model C, adiponectin and transthyretin were removed from model A.

  • PB, postbreakfast;TNF-α, tumor necrosis factor-α.
