Multiple linear regression to test the ability of serum cytokines in predicting the number of self-reported symptoms.
| Cytokine | β | Value of p |
|---|---|---|
| Interval to follow-up | −0.01 | 0.248 |
| Age | −0.03 | 0.276 |
| Sex (male) | −3.40 | 0.00005 |
| BDNF | −2.42 | 0.092 |
| EGF | −0.09 | 0.921 |
| CCL11 | −0.17 | 0.878 |
| IFN-α2 | −2.43 | 0.023 |
| IL-8 | 1.10 | 0.194 |
| IL-10 | −2.34 | 0.307 |
| IL-17 | −0.47 | 0.839 |
| IP-10 | 2.90 | 0.087 |
| MCP-1 | −1.49 | 0.381 |
| MIP-1α | −0.13 | 0.874 |
| MIP-1β | 0.65 | 0.624 |
| TNF-α | 1.76 | 0.420 |
The confounding factors age, sex, and follow-up interval were also included in the model. R2 = 0.20, F (15) = 3.54, p = 1.9 × 10-5. BDNF – ng/dL, other cytokines – pg/dL.
