C1QTNF1 and Sepsis: In agreement with the association between CTRP1 and sepsis, we observed a correlation between CTRP1 and classical markers of inflammation in our cohort, such as interleukin 6 (r = 0.317, p < 0.001), procalcitonin (r = 0.414, p < 0.001), C-reactive protein (r = 0.238, p < 0.001) and suPAR serum levels (r = 0.279, p = 0.001; Table 3), an experimental marker of systemic inflammation [27].
