Variables that predict response of nevus of ota to lasers

Abstract:
Nevus of ota is a dermal melanocytosis common among Asian patients, mottled, blue-gray macule that is usually located unilaterally within the distribution of the first and second branches of the trigeminal nerve and almost always responds well to treatment with Q-switched lasers (eg, ruby, alexandrite, and Nd: YAG). In spite of the plethora of science behind laser-tissue interactions, the objective evaluation of nevus of ota response to laser is not on firm footing and most studies report subjective percentile scoring improvement. A knowledge of the variations in morphology of nevus of ota can help predict an optimal dose response and help to counsel patients appropriately.

Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
