Different case definitions involving pain (general LBP), medication use (M-LBP), seeking healthcare (H-LBP), and lost time (L-LBP) are often used to study LBP outcomes.

Most incident-eligible workers (67%) suffered an LBP outcome during follow-up. Cases decreased from 420 for LBP (25.4 cases\/100 person-years) to 303 for M-LBP (22.0 cases\/100 person-years), to 151 for H-LBP (15.6 cases\/100 person-years), and finally to 56 for L-LBP (8.7 cases\/100 person-years). Conversely, pain intensity and duration increased from LBP to H-LBP. However, pain duration was relatively lower for L-LBP than for H-LBP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Patterns of cases, pain intensity, and pain duration suggest the influence of the four outcomes.
