FGF21 and diabetes mellitus: In a sensitivity analysis, we used continuous values of blood biomarkers instead of quartiles in the multivariable adjustment, and the results were materially changed: the ORs (95% CIs) for diabetes with per-log increment in FGF-21 levels were 1.15 (0.91–1.45) in the total population, 0.80 (0.53–1.23) in men and 1.43 (1.00–2.05) in women (data not shown).
