Table 2 Multivariable logistic regression to identify variables independently associated with HTLV-1 seropositivity in 605 maintenance hemodialysis patients from four satellite clinics in Salvador, Bahia, Brazil

From: Prevalence and risk factors for Human T-Lymphotropic Virus Type 1 (HTLV-1) among maintenance hemodialysis patients

  1. Nine variables were selected to enter the automated, forward stepwise multivariable logistic regression model based on a p value ≤ 0.25 on univariate analyses: age (continuous), gender (female as reference), marital status (unmarried as reference), time on dialysis, history of blood transfusion (yes/no), seropositivity for hepatitis B or C virus (yes/no), socioeconomic status (“poor or very poor” as reference), level of schooling (“less than high school” as reference), and diabetes (yes / no). History of blood transfusion was limited to available data that reported transfusion only for the previous three months
