Linear mixed model analyses of the associations between burnout and job demands, control and support in two different models for twin analysis, Carlin et al. [20] including both same- and opposite-sex twins.

The models include zygosity as additional covariate (7200 individuals in complete same- and opposite-sex twin pairs). **p<.001, *p<.05, nsnot significant.本研究中的模型将合子性（zygosity）作为额外协变量纳入分析，研究样本包含7200名来自完整同性别及异性别双生子对的个体。 **p<0.001， *p<0.05， ns 代表无统计学显著性。
