The diagnostic yield of the aCGH in four groups of the prenatal samples, divided according to the categories of ultrasound anomalies. The absolute numbers of cases in each of the four groups are shown on X-axis, according to the aCGH results - normal results (grey), VOUS/secondary findings (black) and causative pathogenic CNVs (marble). Y-axis represents the four groups of prenatal samples according to the ultrasound anomalies/measurements. NT - nuchal translucency, IUGR - intrauterine growth restriction
