1, to calculate the accuracy rate of electronic nasopharyngoscopy, the following formula can be used:Accuracy rate = (true positives + true negatives)/(true positives + false positives + true negatives + false negatives) × 100%.
2, where: true positive refers to the number of samples that are actually positive that are correctly identified as positive; false positive refers to the number of samples that are actually negative that are incorrectly identified as positive; true negative refers to the number of samples that are actually negative that are correctly identified as negative; false negative refers to the number of samples that are actually positive that are incorrectly identified as negative.
3. By calculating these values and substituting them into the above formula, the accuracy rate of the eNT can be derived. The accuracy rate is an indicator that assesses the accuracy of the technology in diagnosing throat-related diseases. ElectronicNasoendoscopy is a medical device used to examine the internal structures of the throat and nasal passages. It consists of a flexible fiber bundle and a small camera, which is inserted through the nostrils into the nasal cavity or throat and transmits images to a monitor for the doctor to observe.
