In the results section, the second paragraph should read as:

MR CLEAN, ESCAPE, REVASCAT, and SWIFT PRIME reported the number of subarachnoid hemorrhages [1, 2, 4, 5]. In all trials, these were more frequent in the intervention groups than in the control groups. Endovascular therapy led to a statistically significant higher rate of subarachnoid hemorrhage, regardless of whether the fixed effects model (RR 3.27, 95% CI 1.08–9.91, p = 0.036), or the random effects model (RR 3.19, 95% CI 1.04–9.76, p = 0.042) was considered (Fig. 2).
