“…184 Modelos ainda podem predizer o desempenho desses três marcadores ultrassonográficos (osso nasal, espessura pré-nasal e prega nucal) associados ao teste quádruplo. A sensibilidade estimada chega a 93% para taxa de falsos-positivos de 5%, o que é comparável ao desempenho do rastreamento combinado no primeiro trimestre da gestação 184 .…”
