FIG. 3.

Placental measurements per fetus in control and unilateral pregnant sheep. A) total number of placentomes per fetus and (B) total placentomal weight per fetus in control singletons (C-1), unilateral singletons (U-1), control twins (C-2), unilateral twins (U-2), control triplets (C-3), unilateral triplets (U-3), and control quadruplets (C-4). Bars indicate means ± SEM. Individual data points are shown by circles. Means that do not share a common superscript letter are different (P < 0.05). Based on these results, pregnancies were categorized as either nonrestricted (C-1, U-1, and C-2) or uterine space restricted (U-2, C-3, U-3, and C-4).
