Ans. A. Positive correlation between birth weight and gestational age
Scatter plot of bone SOS vs gestational age, r=0.569, p<0.001 (y=2161+26.2x). (b) Scatter plot of bone SOS vs birth weight, r=0.420, p<0.001 (y=2800+0.113x).
This shows a significant (p≤0.001) positive correlations between SOS and gestational age, birth weight, length, head circumference and tibial length.
