LIF and triple-A syndrome: Compared to non-AAA patients, patients with an AAA had significantly higher median [IQR] levels of plasma factors C1q (59.5 ug/mL [32.8–67.4] vs. 41.1 ug/mL [30.6–57.9], p = 0.001), C4 (686 ug/mL [528–878] vs. 593 ug/mL [275–748], p = 0.001), Factor B (254 ug/mL [180–327] vs. 212 ug/mL [145–272], p = 0.001), Factor H (337 ug/mL [246–438] vs. 302 ug/mL [218–366], p = 0.002), and Factor D (3.59 ug/mL [2.14–5.68] vs. 2.24 ug/mL [1.32–3.34], p = 0.022).
