Performance of the Model in Predicting Limited Health Literacy at Varying Cutoffs of Predicted Probability (N = 225)
| Probability Cutoff | Sensitivity, % | Specificity, % | Positive Likelihood Ratioa | Negative Likelihood Ratiob |
|---|---|---|---|---|
| a The increase in likelihood of having limited health literacy if subject is found to have a positive result (an individual probability equal to or greater than the given cutoff). | ||||
| b The decrease in likelihood of having limited health literacy if a subject is found to have a negative result (an individual probability less than the given cutoff). | ||||
