TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Previous studies demonstrated CHADS2 score and impaired renal function were both associated with ankle-brachial index (ABI)\xa0<\xa00.9 in patients without atrial fibrillation (AF). Hence, we hypothesized the R2CHADS2 score had a significant correlation with ABI\xa0<\xa00.9 and the aim of this study was to validate this association in non-AF patients.', 'A total of 1482 patients without AF were included. ABI was measured using an ABI-form device. Peripheral arterial occlusive disease (PAOD) was defined as ABI\xa0<\xa00.9 in either leg.', 'Of the 1482 subjects, the prevalence of ABI\xa0<\xa00.9 was 5.6%. Multivariate analysis showed that increased age (odds ratio [OR], 1.049; P\xa0<\xa00.001), decreased estimated glomerular filtration rate (OR, 0.978; P\xa0=\xa00.006), and increased R2CHADS2 score (OR, 1.738; P\xa0<\xa00.001) were associated with ABI\xa0<\xa00.9. In addition, in patients with CHADS2 score\xa0≧\xa02, the presence of chronic kidney disease (CKD) was significantly associated with ABI\xa0<\xa00.9 (P\xa0≦\xa00.006), but in patients with CHADS2 score\xa0<\xa02, there was no such association (P\xa0=\xa00.357).'] Is r2CHADS2 score significantly associated with ankle-brachial index < 0.9 in patients without atrial fibrillation?
OUTPUT:
