Figure 3.

Comparison of mean fetal and placental mass to maternal exogenous CO exposure. Mean fetal mass for each CO exposure level is displayed in figure A, with a significant decrease in mass observed only at 400 ppm (* p < 0.05). Mean placental mass for each CO exposure level is displayed in figure B; no significance at any of the CO exposures was observed (p > 0.05).
