a: Pooled analysis forest plot under the fixed effects model, showing a statistically significant reduction in the odds for mild complications in robotic compared to the open approach (petoOR = 0.52, CI95% [0.43; 0.64]). b: Corresponding meta-regression analysis bubble plot and regression line, along with its 95% confidence interval, depicting the annual change in the overall estimate of the effect in log scale. This graph demonstrates a statistically significant difference between the two approaches that is progressively expanding beyond 2014. According to this finding, patients undergoing robotic partial nephrectomy are less prone to the development of mild postoperative complications (CD: I and II) compared to those undergoing conventional open surgery, with the relative benefit becoming larger and larger over the years.
