Marinus J.C. Eijkemans mainly focuses on Gynecology, Internal medicine, Obstetrics, Logistic regression and Endocrinology. His Gynecology research integrates issues from In vitro fertilisation, Infertility, Antral follicle, Live birth and Hazard ratio. His research in Obstetrics intersects with topics in Clinical trial, Intention-to-treat analysis, Internal validation, Artificial insemination and Medical physics.
His study looks at the intersection of Logistic regression and topics like Econometrics with Statistical model. Marinus J.C. Eijkemans works mostly in the field of Endocrinology, limiting it down to topics relating to Amenorrhea and, in certain cases, Menstrual cycle, Premature ovarian failure, Ovulation induction, Free androgen index and Ovulation. He focuses mostly in the field of Statistics, narrowing it down to matters related to Discriminative model and, in some cases, Sample.
Marinus J.C. Eijkemans mainly investigates Internal medicine, Gynecology, Obstetrics, Endocrinology and Surgery. His research integrates issues of Oncology and Cardiology in his study of Internal medicine. His work deals with themes such as In vitro fertilisation, Fertility, Ovarian reserve, Infertility and Live birth, which intersect with Gynecology.
His In vitro fertilisation study integrates concerns from other disciplines, such as Andrology, Embryo transfer, Stimulation and Pregnancy rate. Marinus J.C. Eijkemans interconnects Logistic regression, Randomized controlled trial, Intention-to-treat analysis and Cohort in the investigation of issues within Obstetrics. His work in Surgery covers topics such as Odds ratio which are related to areas like Proportional hazards model.
His primary scientific interests are in Internal medicine, Sample size determination, Gynecology, Clinical trial and Cohort. His Internal medicine research is multidisciplinary, relying on both Endocrinology and Oncology. To a larger extent, Marinus J.C. Eijkemans studies Statistics with the aim of understanding Sample size determination.
The study incorporates disciplines such as In vitro fertilisation, Anti-Müllerian hormone, Live birth, Obstetrics and Fetus in addition to Gynecology. His In vitro fertilisation research is multidisciplinary, incorporating elements of Standard treatment and Pregnancy rate. His studies in Obstetrics integrate themes in fields like Intention-to-treat analysis, Intracytoplasmic sperm injection, Breast cancer and Uterine cavity.
His primary areas of investigation include Internal medicine, Sample size determination, Cohort, Clinical trial and Confidence interval. Many of his studies on Internal medicine apply to Oncology as well. His study on Sample size determination is covered under Statistics.
His Cohort research incorporates themes from Odds ratio, Small for gestational age, Prospective cohort study, Gestational diabetes and Physiology. His study focuses on the intersection of Disease and fields such as Age at menopause with connections in the field of Gynecology. His Gynecology research includes elements of Free androgen index, Polycystic ovary and Menopause.
