Figure 2 is a flow diagram that outlines the study retrieval and selection process. It consists of boxes with text that describes the study selection process from the total number of citations retrieved from the literature searches to the number of studies that satisfied the inclusion criteria of the report. This figure is described further in page 25 of the results section as follows: “The search strategy identified 10,745 citations from electronic databases. Screening based on titles and abstracts identified 1,273 potentially relevant studies. We identified 17 additional studies by hand searching the reference lists from included studies, conference proceedings, and clinical trial registries. The full text of 35 studies could not be retrieved through the university interlibrary loan service. Therefore, the full texts of 1,255 potentially relevant reports were retrieved and evaluated for inclusion in the review. Using the detailed selection criteria, 140 studies were included, and 1,115 were excluded. Of the 140 included studies, 59 were identified as companion publications; therefore, 81 unique studies were included. The most frequent reasons for exclusion were: 1) ineligible age of study participants (N = 824); 2) the article did not report on primary research (N = 95); 3) ineligible study design (N = 82); 4) the study did not compare two antipsychotic drugs or an antipsychotic drug with placebo (N = 45); 5) no outcome data of interest were reported (N = 29); and 6) study participants were not diagnosed with any of the conditions of interest (N = 20). Twenty studies were excluded for other reasons.”
