“…The SAMe-TT 2 R 2 score has been assessed in 15 exclusively AF cohorts, [174][175][176][177][178][179][180][181][182][183][184][185] with six 175,177,179,180,183,186 reporting its predictive ability to forecast good or poor anticoagulation control, with c-statistics ranging from 0.56 180 to 0.72. 172 However, these cohorts were predominantly elderly, Western (white) populations, and its predictive ability in non-Western populations has relatively limited data as only 3 studies have assessed it, 174,175 with only 1 reporting c-statistics (c-statistic, 0.54; 95% CI, 0.52-0.57).…”
