From: CXCL9, a promising biomarker in the diagnosis of chronic Q fever
Circulating chemokines in serum. Circulating levels of chemokines, medians with interquartile range are indicated. Panel (a–d) display CXCL9, CXLC10, CXCL11 and CCL8 serum levels respectively, in healthy controls (n = 9), past Q fever individuals (n = 10), acute Q fever (n = 9), and chronic Q fever (n = 51). Kruskal Wallis with Dunn’s multiple comparisons test was performed. Panel (e) represents the Receiver Operating Characteristic (ROC curve) of CXCL9 concentration in serum in chronic Q fever patients or past Q fever individuals. *: p < 0.05, **: p < 0.01, ***: P < 0.001, ns: not significant
