Figure 2

Reviewing the graph illustrating the time-dependent effect of oral morphine consumption on the development of the thickness of the fetal portion of the placenta for three different periods of pregnancy (9-day, 10-day, and 14-day pregnant mothers), and a comparison between the experimental (E) groups and the control (C) groups reveals the reduction of the fetal portion of the placenta in the experimental group, compared to that of the control groups ((a) value of <0.01 indicating a significant difference).
