The PICA\u2013SCA anastomosis was significantly associated with independent functional outcome at 90 days (67\/196 (34.2%) vs 109\/450 (24.2%), adjusted OR (aOR) 1.80 (95% CI 1.13 to 2.86), p=0.01) and was significantly associated with a decreased rate of SICH (40\/442 (9.0%) vs 5\/193 (2.6%), aOR 0.29 (95% CI 0.11 to 0.76), p=0.01). No significant difference was found between PICA\u2013SCA anastomosis and 90-day mortality (219\/450 (48.7%) vs 80\/196 (40.8%), aOR 0.72 (95% CI 0.48 to 1.08), p=0.11). Subgroup analysis showed that the association between independent functional outcome and PICA\u2013SCA anastomosis was strongest in patients with middle BAO (27\/77 (35.1%) vs 22\/118 (18.6%), aOR
