Prognostic factors associated with gastrointestinal dysfunction after gastrointestinal tumor surgery: A meta-analysis

Figure 1 Flow chart of the literature screening. ¹Consider, if feasible to do so, reporting the number of records identified from each database or register searched (rather than the total number across all databases/registers). ²If automation tools were used, indicate how many records were excluded by a human and how many were excluded by automation tools.
