Question: | OB/GYN (n = 114) % [95% CI] | MFM (n = 29) % [95% CI] | GP (n = 31) % [95%CI] | MW (n = 14) % [95% CI] | p-value |
---|---|---|---|---|---|
Correctly identified that detection rates are NOT equal for different trisomies such as 13, 18, and 21 using cfDNA. | 53.5% [44.2–62.5] | 82.8% [64.1–92.8] | 41.9% [25.8–60.0] | 14.3% [3.4–44.3] | p = 0.000 |
Correctly identified that cfDNA has a better detection rate for Trisomy 21 than currently available prenatal screening methods such as the First Trimester Combined Test or Integrated Prenatal Screening. | 88.5% [81.1–93.2] | 100.0% | 67.7% [49.3–81.9] | 50.0% [25.1–74.9] | p = 0.000 |
Correctly identified that NOT all the chromosomal abnormalities diagnosed via amniocentesis can also be readily detected via cfDNA. | 85.0% [77.0–90.5] | 96.6% [78.4–99.5] | 61.3% [43.0–76.8] | 71.4% [42.7–89.4] | p = 0.017 |
