Regular consumption of cod liver oil is associated with reduced basal and exercise-induced C-reactive protein levels; a prospective observational trial

Table 3 Association between regular use of any omega-3 fatty acid supplements (n = 274) and change in concentrations of Ln-transformed CRP (B (95% confidence interval)) compared with non- or sporadic users (n = 582)

	Model 1	Model 2	Model 3	Model 4
CRP baseline
Regular use of any omega-3	−25 (−27- -12), p < 0.001	−25 (−28- -13), p < 0.001	−18 (−30- -7), p = 0.002	−19 (−31- -7), p = 0.002
CRP 24 h post-race
Regular use of any omega-3	−25 (−37- -14), p < 0.001	−23 (−34- -11), p < 0.001	−16 (−26- -5), p = 0.004	−16 (−26- -5), p = 0.003
Delta CRP 0-24 h
Regular use of any omega-3	−27 (−40- -14), p < 0.001	−24 (− 27- -11), p < 0.001	−17 (− 28- -5), p = 0.006	−16 (− 28- -5), p = 0.006

Model 1: Unadjusted, Model 2: adjusted for age and sex, Model 3: As for Model 2, but also adjusted for body mass index and race duration, Model 4: As for Model 3, but also adjusted for delta creatine kinase (baseline-24 h post-race), MET hours per week, resting heart rate and higher education
