Fig. 4. Comparison of complications rates (hardware-related, neurological, and surgical-site complications) between minimally invasive and open lumbar spinal fusion. Heterogeneity: hardware-related complications [τ2=0.000; χ2=4.922, df=10 (p=0.896); I2=0.0%], neurological complications [τ2=0.000; χ2=3.909, df=9 (p=0.917); I2=0.0%], surgical-site complications [τ2=0.000; χ2=5.232, df=8 (p=0.732); I2=0.0%], and overall complication rates [τ2=0.000; χ2=16.605, df=29 (p=0.968); I2=0.0%]. df, degrees of freedom; OR, odds ratio; CI, confidence interval.
