How Obesity studies are organized in the registry
Obesity research spreads across several neighboring registry terms — “overweight,” “weight loss,” and “metabolic syndrome” all label closely related studies — so checking more than one term gives a fuller picture. The portfolio includes many behavioral and lifestyle studies alongside drug trials, which makes the study-type filter (interventional vs. observational) more informative than usual.
- 18% of the 970 locally indexed Obesity records are currently marked recruiting.
- The most common phase group in the local index is Not applicable (472 records).
- The most frequent sponsor is Novo Nordisk A/S (76 records).
- The most listed study location is Dallas, Texas (97 records).
