An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

The disease, disorder, syndrome, illness, or injury that is being studied.
Patients with irritable bowel syndrome (IBS) often benefit from dietary changes. Since it has been shown that a gluten free diet (GFD) often alleviates the clinical symptoms, an overlap between patients with IBS and non-celiac glutensensitivity is assumed. The study includes 25 healthy individuals and 150 patients with IBS taking a six week GFD. Participants fill in questionnaires to determine clinical symptoms and psychological well being at the beginning and end of the dietary intervention. Patients with symptom relief under diet are further provoked in a double-blind placebo-controlled study with gluten or placebo containing bars for three weeks, separated by two weeks of washout to diagnosis of NCGS. In addition, peripheral mononuclear cells are isolated at the beginning and end of the diet and the stimulating potential of wheat gluten is analyzed.
