Two-way ANOVA. Multiple comparisons for fetal body weight and GA within pumped and pumpless AP circuits and between the intervention groups: ab p < 0.05. *p < 0.05 body weight is significantly different between pumped and pumpless AP circuits within intervention groups (i.e., body weight maintained on a pumped AP circuit vs. body weight maintained on a pumpless AP circuit). Interpretation of numbers for multiple comparisons: a represents a statistically significant difference compared with b.
