Network linkages between meta-analyses and the included studies based on trial classifications. A This network graph shows meta-analyses (black circles, nodes) and links with included studies (edges, for green, blue, red, and grey circles) based upon trial classification. The size of the circles represents either the number of studies included in the meta-analysis (for meta-analyses) or the number of times an article appears across different meta-analyses (for green, cyan, red, and grey circles). Red circles represent self-identified pilot studies; Green circles represent trials N ≤ 100; Grey circles represent trials N > 100 and N ≤ 370; and Cyan circles represent trials N > 370. B Network linkages between meta-analyses and included studies based on topic investigated in the meta-analyses. Red circles represent meta-analyses on a topic related to obesity; Green circles represent topics related to diet; Orange circles represent topics related to motor skill/fitness; Blue circles represent topics related to physical activity; Yellow circles represent topics related to sedentary/screen time behaviors. The size of the circles represents either the number of studies included in the meta-analysis or the number of times an article appears across different meta-analyses. C Example of network linkages between two meta-analyses and the overlap and non-overlap of the articles included. Yellow and cyan circles represent studies included within the meta-analysis that are not included in the other meta-analysis (non-overlap). Green circles represent studies included in both meta-analyses
