The graph has two axes. The horizontal axis shows study, labeled Polymer pad and Micro Pulse. The vertical axis shows Odds ratio, scale numbered 0, 0.5, 1, 1.5. There is a horizontal line through odds ratio = 1. For each of the two studies, there is a point marked showing the odds ratio and a vertical line through this showing the confidence interval. For Study = Polymer pad, odds ratio = 0.46, vertical line goes from 0.26 to 0.82. For Study = Micro Pulse, odds ratio = 0.32, vertical line goes from 0.08 to 1.22. This crosses the horizontal line at 1.0.
