The graph has two axes. The horizontal axis shows study, numbered 1, 2, 3, 4. The vertical axis shows Relative risk, scale numbered 0, 1, 2, 3, 4, 5. There is a horizontal line through relative risk = 1. For each of the four studies, there is a point marked showing the relative risk and a vertical line through this showing the confidence interval. For Study = 1, relative risk = 1.0, vertical line goes from 0.53 to 1.90. For Study = 2, relative risk = 1.4, vertical line goes from 0.76 to 2.58. For Study = 3, relative risk = 1.8, vertical line goes from 1.00 to 3.28. This just touches the horizontal line at 1.0. For Study = 4, relative risk = 2.8, vertical line goes from 1.50 to 5.21.
