Follow-up outcomes
The pooled estimates of postoperative stroke and SCI were 5%
(95%
CI 4 – 7; I2 = 63.93%) and 3% (95% CI 2 –
4; I2 = 19.56%), respectively (Figure 2). The
pooled estimates of acute kidney injury, bleeding, and in-hospital
mortality were found to be 12% (95% CI 9 – 15;I2 = 86.65%), 6% (95% CI 3 – 8;I2 = 71.05%), and 7% (95% CI 5 – 9;I2 = 68.65%), respectively (Figure 3).
