Group B had a higher rate of aortic root replacement (44% vs 35%, P = .008), lower ascending aorta and hemiarch replacement (40% vs 53%, P = .013) and showed a trend towards more extensive distal aortic repairs: total arch replacement (27% vs 20%, P = .139) and frozen elephant trunk (20% vs 14%, P = .171).

did not reach statistical significanceP = .25not close (p > 0.1)

There were 30 intraoperative deaths (part of the overall mortality), with 21 (8.9%) in the pre-Rota group and 9 (5.3%) in the post-Rota group; this difference did not reach statistical significance ( P = .25).

a possible trendno p-value reported

However, a reduction in aortic-specific mortality in the post-Rota group approached statistical significance ( P = .052), suggesting a possible trend towards improved aortic-related outcomes following implementation of the Aortic Rota.
