Impact of only low back pain (LBP only), only upper extremity complaints (UED only), and low back pain with musculoskeletal upper extremity co-morbidity (LBP with UE) on general health (PCS12, MCS12) and health related quality of life (EQ5d and EuroQol-Vas) compared to those without low back pain or upper extremity complaints (no MSD) among industrial workers (n = 505)
