Agreement between automated and manual/clinical aTFA measurements calculated by FTS and FNTS. The best performances, compared with clinical measurements, are highlighted with *. (Pre-op: Pre-operative; Post-op: Post-operative; M: manual; A: automated; C: clinical; ICC: intra-class correlation coefficient; MAD: mean absolute difference; BAA: Bland-Altman analysis; n: number of individuals; CI: confidence interval; SD: standard deviation)
