Bold: P < .10. The history and physical examination forms included categorical variables with possible answers: “no, little, very, very much.” These variables were dichotomized using a cutoff point between “little” and “very.” Categorical variables with possible answers: “no, little, almost normal, normal” were dichotomized using a cutoff point between “no” and “little.” Diarrhea was characterized as reported diarrhea more than twice a day. Decreased urine production was considered if micturition was much decreased or if there was no micturition at all. Income was categorized before the analysis in net income per month: “<450,” “451 to 635,” “636 to 860,” “861 to 1135,” “1136 to 1600,” “1601 to 2270,” “>2270 Euro.”
