GRADE summary of findings for choosing which fetus to use to date twin and triplet pregnancies. Evidence statement Evidence was identified for all fetal ultrasound parameters prioritised for consideration in terms of determining gestational age in twin and triplet pregnancies. All evidence came from observational studies which constitute low or very low quality evidence.
With regard to whether the measurements and charts used in singletons were accurate when applied to twins and triplets, no statistically significant differences in size were found between twin and singleton pregnancies using crown—rump length very low quality evidence or biparietal diameter low quality evidence. Significant differences were reported in the head circumference of larger and smaller twins compared with singletons, although this difference did not remain significant when an average of each set of twins was used very low quality evidence.
There was a significant difference between smaller twins and singletons in femur length , but the difference was not significant when comparing the larger twin or the average of each set of twins with singletons very low quality evidence. Gestational age estimation in twins was not statistically significantly different from singletons when dating was carried out by a formula based on femur length, head circumference and abdominal circumference very low quality evidence , but the same formula systematically underestimated gestational age in triplets by 1 day very low quality evidence.
There was no statistically significant difference in dating by day of oocyte retrieval between twin and singleton pregnancies low quality evidence. Similarly, there was no evidence to suggest that any specific fetal measurement in multiple pregnancies was more effective than another in gestational age estimation. The majority of the studies appeared to use date of oocyte retrieval to determine the true gestational age.
