2.4.2. Data extraction and saving

Two independent researchers will produce Microsoft Excel to extract and manage relevant clinical data eventually included in the literature. We are going to extract the following clinical information: title, first author, sample size, year, included population, age, gender, intervention measures, disease course, results, and adverse reactions. If the clinical data of the relevant studies in the literature are insufficient, we will try to contact the relevant authors for integrated clinical information. If we are not able to contact the author, due to a lack of important information, we will exclude the study.
