Figure 2 Mediation effects of frequent lower limb pain/frequent upper limb pain in the association between sharps injuries and X_i. ^aP < 0.05, ^bP < 0.01, ^cP < 0.0001. ₁: High personal burnout level; ₂: High work-related burnout level; ₃: Experience of overtime vs seldom worked overtime; ₄: Doctors vs Nurses and others; ₅: Irregular work shifts vs other work schedules; a_i: The logistic regression coefficient of risk factors for the association between sharps injuries (SI) and risk factors; s_ai: The standard error of a_i; b_i: The logistic regression coefficient of burnout as an adjusted variable with regard to the association between SI and X_i; s_bi: The standard error of b_i. SI: Sharps injurie; FLLP: Frequent lower limb pain; FULP: Frequent upper limb pain.
