Untreated patients (n=101) stratified by baseline TTR threshold value of 18 mg/dL.
Median OS for TTR ≥18 mg/dL was 4.1 y (95% CI, 3.6-5.5 y) and for TTR <18 mg/dL was 2.8 y (95% CI, 1.4-4.0 y)
Median OS for TTR ≥18 mg/dL was 4.1 y (95% CI, 3.6-5.5 y) and for TTR <18 mg/dL was 2.8 y (95% CI, 1.4-4.0 y)
