a) DAG of need for prosthodontic care (outcome; blue rectangle with black frame) and untreated decay and need for periodontal care (exposures; green rectangles with black frame). SES, dental visits and health insurance are the confounders to be controlled in the multivariable model (grey rectangles), (b) DAG of daily life (outcome; blue rectangle with black frame) and need for prosthodontic care, untreated decay, need for periodontal care (exposures; green rectangles with black frame). SES and age are the confounders to be controlled (grey rectangles). The figures include other variables with potential relationships to the outcomes which were measured in the study (other green rectangles) or not (white ovals)
