CRP and Behcet disease: The BD group as a whole had a mean CRP concentration of 0.40 ml/dl (± 0.73 mg/dl SD; 95% CI 0.30 to 0.50), with significantly elevated CRP levels during manic episodes after correction for multiple comparison [ANOVA, F (2, 216) = 5.888, p = 0.003] (see Fig. 1) compared to euthymic and depressed episodes.
