CRP and rheumatoid arthritis: For DAS28-CRP, the OR of RA disease activity was 0.29 (95% CI: 0.10–0.87) for the olive oil food group and 0.30 (95% CI: 0.10–0.88) for the nuts food group; this means that the odds of having an active disease (according to DAS28-CRP) was significantly lower in the highest tertile categories of consumption for both olive oil and nuts, compared to the lowest tertile categories.
