Allometric relationships between villous membrane diffusive conductances and fetal mass, Mf. Values represent allometric exponents (B) and constants (A) calculated from log-linear regression equations
| Conductance | Exponent B (SEM) | Constant A | P-value (B is not 1) |
|---|---|---|---|
| Villous trophoblast | 1.016 (0.0339) | 0.0222 | NS |
| Villous stroma | 1.079 (0.0367) | 0.0237 | * |
| Villous membrane | 1.040 (0.0334) | 0.0116 | NS |
NS, not significantly different from B = 1
P < 0.05.
