Fig. 1From: TCF7L2 correlation in both insulin secretion and postprandial insulin sensitivityPlasma concentrations of glucose (a), insulin (b), proinsulin (c), C-peptide (d) and glucagon (e) in 26 and 30 carriers of the CC and CT/TT genotypes, respectively, during the mixed-meal test. CT/TT subjects, compared with CC individuals, had higher plasma levels of insulin and C-peptide at 30–120 min (p < 0.05) and proinsulin at 45–240 min (p < 0.05)Back to article page
