Skin Irritation Data
Description
The data set is a re-simulated part from an ongoing neuodermatitis study where researchers investigate the efficacy of an ointment in reducing the severity of skin irritation on the backs of the hands of 25 neurodermatitis patients, where 10 patients’ backs of the hands were rubbed with the ointment and 15 were not. The response is a BI-RADS rating score and the lower the score the better the clinical record. Every remarkable skin irritation was graded on every patients back of the hands and thus, the numbers of replicates differ across the patients.
