Hypothesis

Is there an association between early reduction in painful physical symptoms and long-term depression outcomes in patients treated with duloxetine?

Conclusion

Pain reduction after 2 and 4 weeks can be used to estimate outcomes of long-term treatment with duloxetine.

Supporting Evidence

  • 80% of patients had moderate to severe overall pain at baseline.
  • A 50% reduction in overall pain after 4 weeks was associated with a 13.32 points higher mean KUSTA score after 6 months.
  • Patients with a ≥ 50% reduction in overall pain VAS during the first 4 weeks had a higher chance of achieving a 50% reduction in the IDS-C total score after 6 months.

Takeaway

If people with depression feel less pain after starting treatment, they are more likely to feel better in the long run.

Methodology

Potential Biases

Selection bias due to the non-randomized nature of the study.

Limitations
