Fig 3. Serum creatinine is increased during pneumoperitoneum compared to baseline.

Forest plot of studies comparing serum creatinine during pneumoperitoneum with baseline measurements in the same animals. Effect size is calculated as mean difference (MD) in serum creatinine in mg/dl, and corresponding 95% confidence intervals (95%CI). Weights are from random effects analysis. m = duration of PnP in minutes at time of measurement.
