Threshold effect analysis of OBS and dietary OBS on the cobalt level in ≥70 participants using the two-piecewise linear regression model.
| Adjusted β (95%CI) | P-value | |
|---|---|---|
| OBS infection point | 16.3 | |
| OBS < 16.3 | −1.904 (−3.261, −0.548) | 0.0066 |
| OBS > 16.3 | 0.060 (−0.660, 0.780) | 0.8711 |
| Log likelihood ratio | 0.029 | |
| Dietary OBS infection point | 8.7 | |
| Dietary OBS < 8.7 | −5.184 (−7.497, −2.871) | <0.0001 |
| Dietary OBS > 8.7 | 0.053 (−0.510, 0.615) | 0.8548 |
| Log likelihood ratio | <0.001 |
