In multivariate analysis, serum AFP level (β ± SE = 0.34 ± 0.15, p = 0.03), as well as being unable to work or being disabled (β ± SE = 3.63 ± 1.81, p = 0.04), were the two variables independently positively associated with a high anxiety and depression score (Table S4). Here, AFP is linked to depressive symptom measurement.
