Details

Lo, Wong, Leung, Law, and Yip (2004) describe a case of a 50-year-old man who reported to the emergency department of a hospital with abdominal pain.

However, it is an empirical question.

To test the hypothesis that an eel might cure constipation, we could do a randomized controlled trial. Our outcome variable would be 'cured' vs. 'not cured'. The main predictor variable would be the intervention condition (eel treatment arm vs. waiting list/no treatment arm). We might also factor in how many days the patient had been constipated before treatment (a proxy of symptom severity). The (fictional) data contains the following variables:
