TABLE 3.
Phenotypic (below diagonal) and genetic (above diagonal) correlation coefficients (SE) between fetal thyroid hormone levels, VL, BW, and brain:liver ratio.
| Traits | T3 | T4 | VL | BW | Brain:liver |
|---|---|---|---|---|---|
| T3 a | 0.48 (0.21) | −0.84 (0.38) | 0.10 (0.20) | −0.99 (1.90) | |
| T4 b | 0.39 (0.03) | −0.77 (0.26) | 0.67 (0.17) | −0.79 (1.74) | |
| VL c | −0.38 (0.04) | −0.35 (0.04) | 0.44 (0.41) | −0.97 (0.78) | |
| BW d | −0.01 (0.04) | 0.26 (0.04) | 0.12 (0.05) | −0.83 (0.92) | |
| Brain:liver e | −0.16 (0.04) | −0.19 (0.04) | −0.25 (0.05) | −0.71 (0.12) |
a
Triiodothyronine (T3, ng/dL) levels were measured in serum at 12 or 21 DPMI.
b
Thyroxine (T4, µg/dL) levels were measured in serum at 12 or 21 DPMI.
c
Viral load (VL, log10viral load) was measured in the fetal thymus at 12 or 21 DPMI.
d
Fetal body weight (BW, grams) was measured at 12 or 21 DPMI.
e
Fetal brain to liver ratios were calculated based on weights measured at 12 or 21 DPMI.
