From: Fetal Down syndrome screening models for developing countries; Part II: Cost-benefit analysis
Screening / Diagnostic Tests | Type of distribution | Sensitivity | Specificity |
|---|---|---|---|
FTS | beta | 0.792 | 0.932 |
STS (Triple screen) | beta | 0.762 | 0.908 |
Independent screen (I-S) | beta | 0.784 | 0.925 |
Contingent screen (C-S plus STS) | beta | 0.849 | 0.923 |
NIPS [12] | beta | 0.990 | 0.980 |
