  • *The ORs presented are mutually adjusted for all the risk factors included in the logistic regression models.

  • †‘HEALTHY’ group: subjects working at baseline and without pain in upper limbs or clinically diagnosed UL-MSD. ‘PAIN’ group: subjects working at baseline with pain in an upper limb but without clinically diagnosed UL-MSD. ‘UL-MSD’ group: subjects working at baseline with a clinically diagnosed UL-MSD.

  • UL-MSD, upper limb musculoskeletal disorder.
