There are different tools, methods, and types of analyses in modern clinical studies that can be utilized to obtain important data and achieve positive outcomes. For example, univariate and multivariate analyses can be constructive in various treatment stages of severe illnesses, such as depression. Depression is a severe mental illness that can lead to many negative consequences if left untreated, which is why early diagnosis of this condition is critical in medical terms. Thereby, this paper presents the use of univariate and multivariate analyses in clinical studies related to the early diagnosis of depression among young adults between 18 and 40 years old in primary care practice. Univariate and multivariate analyses can be used in the early diagnosis of depression among adults to reach consistent and accurate results.
