Binary dependent variables: MSDs in the neck, shoulder/upper arm, wrist/hand, and lower back in the last 7 days (yes/no). Method used: GEE: generalized estimating equation. For the remaining anatomical sites: for the elbow/forearm, for the upper back, for the hip/thigh, for the knee/lower leg, and for the ankle/feet.
