Comparison of age-adjusted and multivariable adjusted HR for cancer risk by work-related stress (Karasek), social network, and quality of life indicators. Estimates from Cox proportional hazard models using age as time scale. Multivariable adjusted estimates were adjusted for educational status, smoking status, BMI, recreational physical activity, and alcohol intake. HRs are interpreted as the relative hazard of cancer at higher scores (indicating a higher risk of work-related stress, larger social network, and better quality of life), compared with lower scores. HRs differing from 1 with an unadjusted P < 0.05 are labelled.
