I n our recently published paper in the Journal of Hypertension [1] we investigated the cross-sectional and longitudinal association of fatty liver disease (FLD) with blood pressure (BP) and hypertension in a general population cohort. Furthermore, we analyzed the specific contribution of alcohol consumption to this association. We drew four main conclusions: first, FLD as evidenced by liver hyperechogenicity and increased serum alanine aminotransferase (ALT) levels is associated with BP-related variables and hypertension at baseline. Second, FLD predicts the progression of BP and the development of hypertension after 5 years. Third, alcohol consumption has a minor contribution to the association of FLD with BP-related variables and hypertension. Fourth, the findings emphasize the necessity to implement liver ultrasound in routine medical care to detect FLD if ALT levels are elevated.Due to two errors in our analyses we have to withdraw the second and fourth conclusion. First, we mistakenly did not adjust for BP measurement at baseline or excluded prevalent cases at baseline. Therefore, no proper inferences were possible on any progression of BP and incident hypertension. Second, due to an error in the analysis syntax, an incomplete subset of individuals was included in regression models. We re-analyzed our data using appropriate methods. All corrected tables are displayed below.Whereas higher BP values and higher odds ratios for increased systolic BP, increased diastolic BP and hypertension in longitudinal analyses were observed among individuals with FLD as evidenced by liver hyperechogenicity and increased ALT levels compared to individuals without FLD, all effect sizes were small (Tables 1 and 2). The only statistically significant associations concerned diastolic BP in the whole study population (Table 1) and systolic BP in the subgroup of individuals not receiving antihypertensive medication (Table 2). In this subgroup, the association of FLD with diastolic BP was borderline significant (P ¼ 0.08). Although these results give some support to our hypothesis that FLD is associated with progression of BP and incident hypertension, we cannot maintain our previous conclusion that FLD is a strong risk factor for the progression of BP over TABLE 1.
