Figure 4
A line graph titled Sensitive analysis. The horizontal axis is labeled Remove study and ranges from 0 to 60. The vertical axis is labeled 95% Confidence Interval and ranges from 0.0000 to 0.6000. The graph features two data lines: one for the Lower limit marked with blue circles and another for the Upper limit marked with orange circles. The Lower limit line remains relatively stable around the 0.3000 mark, with slight fluctuations. The Upper limit line stays around the 0.5000 mark, also with minor variations. Both lines show consistent trends without significant deviations across the range of studies removed.Sensitive analysis. Source: Authors’ own work
