Errors occurred in the number of patients in the posterior circulation ischemic stroke (PCIS) group and non-PCIS group described in the original publication [1]. A correction of the data has been made to the Abstract, Results (Section 3.1, first paragraph), Table 1 and Figure 1.
Text Correction
In Abstract, the sentence “They were assigned to the posterior circulation stroke (49 patients) and non-posterior circulation stroke group (159 patients) based on clinical presentation and diffusion-weighted imaging (DWI)” should be replaced with “They were assigned to the posterior circulation stroke (59 patients) and non-posterior circulation stroke group (149 patients) based on clinical presentation and diffusion-weighted imaging (DWI)”.
In Section 3.1. Clinicopathologic Characteristics of Enrolled Patients with Posterior ICAS, the sentence “A total of 152 (73.1%) were male patients; there were 159 patients in non-posterior circulation ischemic stroke (non-PCIS) group and 49 patients in PCIS group” should be replaced with “A total of 152 (73.1%) were male patients; there were 149 patients in non-posterior circulation ischemic stroke (non-PCIS) group and 59 patients in PCIS group”.
Table Correction
In the first lines of Table 1, for the non-stroke group (n = 159) should be corrected to (n = 149) and for the stroke group (n = 49) should be corrected to (n = 59). The correct Table 1 is as below:

Figure Correction
In the last lines of Figure 1, for the group of the patiens with non-posterior circulation ischemic stroke, (n = 159) should be corrected to (n = 149), and for the group of patiens with posterior circulation ischemic stroke, (n = 49) should be corrected to (n = 59). The correct Figure 1 is as below:
