Adjusted serum uric acid concentrations by diet group and sex.

<p>The figure shows the adjusted means and 95% CIs of serum uric acid concentrations in meat eaters (163 men and 245 women), fish eaters (159 men and 246 women), vegetarians (156 men and 248 women) and vegans (162 men and 250 women). Serum uric acid concentrations were adjusted for age (20–29; 30–39; 40–49; 50–59; ≥60 years), alcohol intake (sex-specific fifths), BMI (<20; 20–<22.5; 22.5–<25; 25–<27.5; ≥27.5 kg/m²) and calcium intake (sex-specific fifths).</p
