Figure 4
The horizontal axis is labeled “Remove study” and has markings ranging from 0 to 50 in increments of 5 units. The vertical axis is labeled “95 percent Confidence Interval” and has markings ranging from 0.0000 to 0.4500 in increments of 0.05 units. The graph shows two curves labeled upper limit and lower limit in the legend. The first solid curve labeled “Upper Limit” starts from about (1, 0.38), fluctuates slightly while remaining nearly horizontal, passes through points around (5, 0.3750), (15, 0.3700), and (30, 0.3800), shows a small dip near (34, 0.3600), then rises slightly and terminates at about (47, 0.3800). The second solid curve labeled “Lower Limit” starts from about (1, 0.3000), fluctuates slightly while remaining nearly horizontal, passes through points around (5, 0.2950), (15, 0.3000), and (30, 0.3100), shows a small dip near (34, 0.2900), then rises slightly and terminates at about (47, 0.3100). The two curves maintain a consistent vertical separation across all removed studies. Note: All numerical data values are approximated.Sensitive analysis. Source(s): Figure by author
