Document Summary
Learning objectives: the study question, exposure (e), disease (d) and control (c) variables, whether each variable is continuous or categorical, the number of levels in each categorical variable, variables that should be controlled in the analysis stage. In research synopsis or real research paper, describe: C control variable (choose variables that are known determinants of the outcome. ) Some of the common terminology in epidemiology comes from its early history when it was primarily concerned with infectious diseases. For example, we still use the terms exposure (e) and disease (d) to describe determinants (e) and outcomes (d). Control variables (c) are often known determinants of the outcome (d) other than the determinant variable (e) under study. There can be many (c) variables in a model, but there are usually only one (e) and one (d) variable. Control variables: choose control variables that are known determinants of the outcome (d).
