Plasma cytokine and CRP levels by fatigue group (n=222)
| Total Sample (n=222) |
Low Fatigue Group (n=108) |
High Fatigue Group (n=114) |
Statistics | |
|---|---|---|---|---|
| IL-1β (pg/mL) | 4.11 (3.57) | 4.00 (3.33) | 4.22 (3.80) | MWU p=.814 |
| IL-2 (pg/mL) | 8.58 (14.4) | 8.75 (15.0) | 8.42 (13.8) | MWU p=.145 |
| IL-6 (pg/mL) | 23.6 (37.6) | 21.9 (40.3) | 25.2 (34.9) | MWU p=.003 |
| IL-10 (pg/mL) | 26.5 (55.2) | 19.7 (46.4) | 33.0 (61.9) | MWU p=.021 |
| IL-13 (pg/mL) | 6.40 (11.3) | 5.94 (10.2) | 6.84 (12.3) | MWU p=.075 |
| TNFα (pg/mL) | 12.5 (11.5) | 12.2 (11.7) | 12.7 (11.4) | MWU p=.499 |
| CRP (ng/mL) | 12.0 (18.6) | 11.2 (16.7) | 12.8 (20.2) | MWU p=.629 |
Note: CRP = C-reactive protein; IL = interleukin; MWU = Mann Whitney U Test; ng/mL = nanograms per milliliter; pg/mL = picograms per milliliter; TNFα = tumor necrosis factor alpha. Bolded variable differed by fatigue group using a Bonferroni-corrected p < 0.007. None of the plasma cytokine levels were associated with fatigue group in adjusted analyses.
