Bone density, Internal medicine, Bone mineral, Osteoporosis and Breast cancer are his primary areas of study. His study in Bone density is interdisciplinary in nature, drawing from both Medical physics, Lumbar vertebrae and Dual-energy X-ray absorptiometry. His Internal medicine course of study focuses on Endocrinology and Percentile.
The various areas that John A. Shepherd examines in his Bone mineral study include Young adult and Surgery. His Osteoporosis research is multidisciplinary, relying on both Femur, Physical therapy, Activities of daily living, Natural history and Physical examination. His research in Breast cancer intersects with topics in Gynecology and Oncology.
His main research concerns Internal medicine, Breast cancer, Bone mineral, Nuclear medicine and Mammography. John A. Shepherd studied Internal medicine and Endocrinology that intersect with Cohort. His Breast cancer study incorporates themes from Body mass index, Gynecology and Risk factor.
His study looks at the relationship between Bone mineral and fields such as Bone density, as well as how they intersect with chemical problems. John A. Shepherd interconnects Repeatability, Densitometry and Dual-energy X-ray absorptiometry in the investigation of issues within Nuclear medicine. His Mammography research integrates issues from Odds ratio and Radiology.
John A. Shepherd spends much of his time researching Internal medicine, Breast cancer, Endocrinology, Bone mineral and Anthropometry. His biological study spans a wide range of topics, including Type 2 diabetes and Oncology. The Breast cancer study combines topics in areas such as Body mass index and Confidence interval.
His Choline study in the realm of Endocrinology interacts with subjects such as Context. His Bone mineral study integrates concerns from other disciplines, such as Bone density, Randomized controlled trial, Dentistry and Femoral neck. His Anthropometry research includes elements of Optical imaging and Accuracy and precision.
His primary scientific interests are in Internal medicine, Bone mineral, Endocrinology, Obesity and Anthropometry. Internal medicine is closely attributed to Type 2 diabetes in his work. His Bone mineral research includes themes of Pregnancy, Clinical trial, Randomized controlled trial, Pediatrics and Femoral neck.
His study on Vitamin D and neurology is often connected to Context as part of broader study in Endocrinology. His study on Anthropometry also encompasses disciplines like
