In the published article, there was an error in Figure 1 as published. The patient numbers are listed as 377 --> 377 --> 304, but it should say 377 --> 305 --> 304. The corrected Figure 1 and its caption appear below. Patient recruitment and selection flowchart. In the published article, there was an error in Results, Algorithm for Acenocoumarol Dosing in the Chilean Population. In the formula two factors have decimals placed incorrectly. It’s a formatting error, but it is significant as it impacts the dose calculations. The formula previously stated: “Log WTD = 3.081 + (0.167 × men) - (age × 0.081) - (initial INR × 0.55) + (BMI × 0.013) - (CYP2C9*1/*2 × 0.107) - (CYP2C9*1/*3 × 0.323) - (CYP2C9*3/*3 × 0.746) - (VKORC1 G/A × 0.270) - (VKORC1 A/A × 0.701).” The corrected formula appears below: “Log WTD = 3.081 + (0.167 × men) - (age × 0.0081) - (initial INR × 0.055) + (BMI × 0.013) - (CYP2C9*1/*2 × 0.107) - (CYP2C9*1/*3 × 0.323) - (CYP2C9*3/*3 × 0.746) - (VKORC1 G/A × 0.270) - (VKORC1 A/A × 0.701).” In the published article, there was an error in Results, Genotype Distribution in the Study Population, paragraph 1. This sentence previously stated: “The analysis of the HWE showed that only CYP2C9*3 (rs1057910) is in HWE (chi2 = 4.67). All other SNPs, VKORC1 (rs9923231) (chi2 = 0.09), VKORC1 (rs7294) (chi2 = 0.62), GGCx (rs11676382) (chi2 = 1.2), CYP4F2 (rs2108622) (chi2 = 1.02), ApoE (rs429358) (chi2 = 0.08), ABCB1 (rs1045642) (chi2 = 0.68), and CYP2C9*2 (rs1799853) (chi2 = 2.33), are not in HWE.” The corrected sentence appears below: “The analysis of the HWE showed that only CYP2C9*3 (rs1057910) is not in HWE (chi2 = 4.67).
