Odds ratios (OR) for association between fewer days with LBP and fewer episodes of LBP during the past year at follow up and seeking of treatment for LBP at follow up, and the intervention and number of days with LBP during the past year at baseline
| Intervention | Duration of LBP at baseline | |
|---|---|---|
| OR (95% CI)* | OR (95% CI)* | |
| *Controlled for the opposite variable and age. | ||
| Improving one category in number of days with LBP during past year | 0.98 (0.52 to 1.85) | 4.57 (3.22 to 6.46) |
| Improving one category in number of episodes with LBP during past year | 1.01 (0.49 to 1.53) | 1.03 (0.62 to 1.72) |
| Seeking of treatment during past year at follow up | 1.14 (0.69 to 1.89) | 1.69 (1.38 to 2.07) |
