No differences in CRP concentration were found between women and men, ΔMMedian = −0.05 [95% HDI −0.20, 0.09], BF10 = 0.27, or between recurrent and first episode depression, ΔMMedian = 0.06 [95% HDI −0.09, 0.23], BF10 = 0.34 (two-sided), respectively. This evidence concerns the gene CRP and depressive symptom measurement.
