Frequencies and titers of autoantibodies among the three groups. Panel A: Frequencies of M2-AAB was significantly higher in women with severe preeclampsia than in the normal pregnant women and non-pregnant controls. Panel B: Geometric mean titers of M2-AAB was significantly higher in women with severe preeclampsia than in the normal pregnant women and non-pregnant controls. *p < 0.05: women with severe preeclampsia compared to normal pregnant women and non-pregnant controls; ***p < 0.001: women with severe preeclampsia compared to normal pregnant women and non-pregnant controls. M2-AAB: autoantibodies against M2-muscarinic receptors; SPE: severe preeclampsia; NP: normal pregnant; NC: non-pregnant control.
