- DOR, diagnostic odds ratio; LR, likelihood ratio; n, number of patients; SD, standard deviation; SF, symphysis-fundus.
- Accuracy of symphysis-fundus height in predicting severe small-for-gestational-age status (birth weight ≥ two standard deviations below the mean) with 95% confidence intervals.
