Figure 3.
Composite adverse neonatal complication rate among privately and publicly insured women before and after expansion of midwifery and laborist services. This graph shows the rates of composite short term adverse neonatal outcomes (5 minute APGAR <7, umbilical artery pH<7.0, umbilical artery base excess <–12) plotted over time and the model-predicted rates before and after the practice change as predicted by the interrupted-time series analysis. None of the slopes were statistically different from zero.
