Income in midlife and dementia related mortality over three decades: A Norwegian prospective study.

Those in the lowest fifth in the income hierarchy had HR = 1.61 (95% CI 1.53, 1.69) regarding total mortality ( Table 3 , Model T1), and adjustment for education attenuated the association somewhat (HR = 1.37, 95% CI 1.30, 1.45, Table 3 Model T2), and even more when the risk factors were added to the model (HR = 1.27, 95% CI 1.20, 1.34), but the associations were still highly significant (p < 0.001).
