Multivariable-adjusted HRs and 95% CIs for the risk of HT according to dietary intakes of animal, plant, and total protein on a continuous scale. CI, confidence interval; CL, confidence limit; HT, hypertension. (a) Association between animal protein intake and HT risk in men; (b) Association between animal protein intake and HT risk in women; (c) Association between plant protein intake and HT risk in men; (d) Association between plant protein intake and HT risk in women; (e) Association between total protein intake and HT risk in men; (f) Association between total protein intake and HT risk in women. Red solid lines represent the multivariable-adjusted HRs, with black dotted lines representing the 95% CIs. Gray horizontal solid lines represent the references that were set at the median intakes, corresponding to an HR of 1.0. Analyses were adjusted for a series of variables according to Model 3.
