The proportion of individuals with diabetes increased for every quartile (Q) of Gal-4 (Q1 = lowest Gal-4 levels 11.3%; Q2 22.6%; Q3 25.2%, and Q4 = highest Gal-4 levels 40.9%) (Fig. 1) and, compared to all other quartiles, the odds of having diabetes were the highest in the upper quartile (OR 2.65; 1.33–5.30) (Table 4).
