Some people still have COVID virus in their stool months after they recover from the illness. Researchers wondered if the impact on serotonin could be responsible for Long COVID. They decided to study the impact of medications that increase serotonin in the body on Long COVID. Dozier et al. (2024) looked at records of patients who were diagnosed with COVID and happened to be taking a medication for depression that influences serotonin. Of the 302,626 patients, 100,803 of them were taking the medication. They analyzed the patient records to determine which patients developed Long COVID. What would a reasonable hypothesis be for this study? What is the impact of serotonin on Long COVID? Depression medication will decrease Long COVID. Depression causes Long COVID. If a patient is infected with Long COVID, they will develop depression.
