CRP and Guillain-Barre syndrome: Univariate linear regression (Table IV) showed a significant relationship between an increased CRP and the following factors: fever during labor (p<0.001), indwelling catheter (p<0.001), GBS status unknown (p<0.001), anesthesia (p<0.001), intravenous line (p<0.001), scalp electrode (p=0.014), primary caesarean (p<0.001), diabetes (p<0.001), intact perineum (p<0.001), any caesarean (p<0.001), formula feeding (p=0.006), fever in the postpartum (p<0.001), manual removal (p<0.001), twin (p<0.001), endomyometritis (p=0.011) and cystitis (p=0.019).
