Fig. 2: Associations of total protein intake with risk of incident T2D by metabolic diseases at baseline.

HRs were scaled per 1-percentage-point increment in the proportion of energy intake from total protein. Participants were divided into two subgroups via propensity-score matching, including with (dark red) and without (dark blue) A hypertension, B NAFLD, C hyperlipidemia, or D central obesity at baseline. Cox proportional hazards models were adjusted for family history of diabetes and HbA1c (%) at baseline.
