The performance of classifying wear and non-wear events for females versus males
| Method | CR (95% CI) | Sensitivity (95% CI) | Specificity (95% CI) | PPV (95% CI) | NPV (95% CI) |

CR, classification rate; CTA, combining temperature and acceleration; NPV, negative predictive value; PPV, positive predictive value.
