CDKN2B-AS1 and stroke disorder: Conversely, in the dominant inheritance model, a protective correlation was found between the ANRIL-CA genotype and the combined CC + AA genotypes with stroke susceptibility, resulting in an OR of 0.42 (95% CI = 0.239–0.765), RR of 0.64, and a p-value less than 0.0042 (Table 4).
