NOTCH2 and type 2 diabetes mellitus: The NOTCH2 risk allele did not associate with type 2 diabetes incidence in the whole population (HR 0.99; CI 0.91–1.09; P = 0.90); however, it was associated significantly with decreased risk of type 2 diabetes in the fourth fiber intake quintile (HR 0.75; CI 0.60–0.95; P = 0.015) (Table 4).
