Characteristics of the Included Studies
We identified a total of 162 articles through database search (Figure 1
presents the flow chart of the study selection process). After
screening, 10 articles were finally included. Among them, 8 articles
(438 CD patients and 358 healthy controls) and 9 articles (391 UC
patients and 438 healthy controls) have studied the serum resistin
levels. Table 1 presents the basic characteristics of the enrolled
studies.
