Multivariable logistic regression model of risk factors for Cyclospora infection among 68 cases and 120 controls
| Characteristic | OR (95% CI)a | p |
|---|---|---|
| Drank untreated water | 4.2 (1.4, 12.5) | 0.009 |
| Chickens | 1.9 (1.0, 3.7) | 0.054 |
| Contact with soil among | 19.8 (2.2, 182) | 0.008 |
| children <2 years old | ||
| Contact with soil among | 1.4 (0.6, 2.9) | nsc |

aModel adjusted for age category (<2 years, >2 years).
bOdds ratio for persons 2 years or older calculated as (OR for persons <2) *(OR for interaction term for soil contact with age <2). p value for the interaction term = 0.03.
cns = not significant.
