#2755: Effect Size explain

Meta-analysis

Inclusion criteria: All studies

[A forest plot is shown. In the tab on the top right, there is a label “Page 53,589”. On the right side of the plot, there is a vertical scrollbar where the scroll box is about one quarter from the top. A horizontal axis centered on 0 is shown at the bottom and -1 and +1 on either side are labeled. In the middle of the plot, there is a dashed vertical line. On both sides of the vertical line in separate rows, there are black boxes of different sizes with horizontal bars of varying lengths on the sides of the boxes. Below the plot, slightly to the right of the vertical line, there is a black diamond wider than it is tall, labeled “0.17 (-0.14, 0.52)”.]

Bad news: They finally did a meta-analysis of all science, and it turns out it’s not significant.
