Statistical aspects of modeling the labor curve

摘要: In a recent review by Cohen and Friedman, several statistical questions on modeling labor curves were raised. This article illustrates that asking data to fit preconceived model or letting sufficiently flexible observed is the main difference in principles of between original Friedman curve our average curve. An evidence-based approach construct establish normal values should allow data. addition, presence deceleration phase active an was questioned. Forcing be part may have artificially raised speed progression with particularly large impact earlier 4 6 cm. Finally, any illustrative not instructive managing because variations individual pattern errors measuring cervical dilation. With tools commonly available, it more productive new partogram takes physiology contemporary obstetric population into account.
