Baseline characteristics of the studied women (n = 249).
Fig 1.
Comparison of GA obtained at the time of first trimester scan according to the two alternative pregnancy dating methods, on the basis of the IVF procedure (x axis), or on the basis of ultrasound measurement of CRL (y axis).
The continuous oblique line represents the bisect (one should expect cases to be along the line if the two methods coincide). Most cases are located above the line. Intergroup comparison using paired non–parametric Wilcoxon test highlights a statistically significant difference (p<0.001).
