- The crude and adjusted risk ratios calculated using covariates such as the mother’s age, pre-pregnancy BMI, weight gain during pregnancy, parity, smoking and alcohol consumption status, education, and income, to determine the effect of HG on the risk of SGA birth
- RR risk ratio, CI confidence interval
