Table 3 Uni and multivariate linear regression model for serum and salivary ET-1 levels in all enrolled subjects. Age was included as continuous variable. For periodontitis and CHD, controls served as reference. For gender, male served as reference. For education, primary school served as a reference.
From: Analysis of Endothelin-1 Concentrations in Individuals with Periodontitis
