Fig. 3From: Metabonomics profile analysis in inflammation-induced preterm birth and the potential role of metabolites in regulating premature cervical ripeningIdentified metabolic profile in CTL and PTB mice. A Principal component analysis (PCA) showed a distinct metabolic profile in the PTB group compared to the CTL group. X-axis and Y-axis represent the first and second principal components, respectively. B Statistical validation with perripening analysis of the corresponding OPLS-DA model of the PTB and CTL groups. C Perripening tests were obtained from LC–MS data of the PTB and CTL groups. The intercept values of the regression line and the Y-axis are R2 and Q2Back to article page
