TABLE 2.
Example WOE Categories for Models Used to Assess Risk of Fetal Distress After Hurricane Katrina Landfall
| Modela | WOE categoryb |
| M1: Hurricane strength by location, time | A2 |
| M3: Hurricane → psychological stress | A1 |
| M4a: Psychological stress → fetal distress | B1 |
| M4b: Race as factor → fetal distress | B2 |
a
Denotes “causes,” e.g., M3 assumes hurricane landfall causes psychological stress.
b
A = direct evidence for scenario being assessed (Katrina); B = evidence from similar scenario (e.g., results for Andrew, not Katrina); 1 = strong model (accuracy and reliability); 2 = moderate model (important variation, unsure causality, and other unknowns).
