Data collection:
For data collection, the researchers recorded the demographical
charastristics of the enrolled patients, including age, sex, marital
status, educational level, occupation, season of the visit, nationality,
and as well as dermatologic conditions in a researcher-made data
collection form. For assessment the patients’ response to the treatment
we used Patient Global Impression Scale of Improvement (PGI-I).
Furthermore, the researchers called the patients to obtain any missing
information.
