Both of them are conducting randomised trials on a new drug to treat a certain illness. The outcome of interest is days hospitalised. If the treatment is effective, it will lower the amount of days the patient stays in the hospital. For one of the hospitals, the policy regarding the random treatment is to give it to 90% of its patients while 10% get a placebo. The other hospital has a different policy: it gives the drug to a random 10% of its patients and 90% get a placebo. You are also told that the hospital that gives 90% of the true drug and 10% of placebo usually gets more severe cases of the illness to treat. The CSV file contains columns for `hospital` indicating the hospital a patient belongs to, `treatment` signifying if the patient received the new drug or placebo, `severity` reflecting the severity of the illness, and `days` representing the number of days the patient was hospitalized.\",\n \"columns\": {\n  \"hospital\": \"int64\",\n  \"treatment\": \"int64\",\n  \"severity\": \"float64\",\n  \"days\": \"int64\"\n }\n}"}
