Urine (end of the first trimester)
464 (88 spont. PB, 26 ind. PB)
Preterm birth (spontaneous and induced), control
NMR
Spontaneous PB associated with increased urine lysine, clinically induced PB was associated with in overweight and obese women and increased resonance in a N-acetyl glycoprotein
95% confi.int., AUC for SPB: 58.8-59.4%, for IPB: 66%
Higher lactate level in term ALR group compared to term and preterm AHR women, acetate was increased in preterm compared to the term group for SYM and AHR group
P<0.05, acetate integrals in PTB versus term for AHR and SYM group: predictive of preterm birth <37 gestational weeks is AUC of 0.78, acetate integrals in PTB versus term Sym group: delivery within 2 weeks of index assessment AUC of 0.84
