His main research concerns Dentistry, Confidence interval, Survival rate, Retrospective cohort study and Surgery. His work deals with themes such as Implant, Dental prosthesis, Orthodontics and Complication, which intersect with Dentistry. The concepts of his Survival rate study are interwoven with issues in Cumulative incidence and Hazard ratio.
His Retrospective cohort study research is multidisciplinary, relying on both Peri-implantitis, Survival analysis and Incidence. His Surgery research incorporates elements of PR interval and Cardiology. His study with Prospective cohort study involves better knowledge in Internal medicine.
Marcel Zwahlen mainly investigates Internal medicine, Surgery, Pediatrics, Cohort study and Confidence interval. His biological study spans a wide range of topics, including Gastroenterology, Endocrinology and Oncology. The Surgery study combines topics in areas such as Observational study and Cardiology.
His studies deal with areas such as Cancer, Epidemiology and Childhood Cancer Registry as well as Pediatrics. His Confidence interval research includes themes of Survival rate, Retrospective cohort study and Dentistry. His Dentistry research incorporates themes from Poisson regression, Dental prosthesis, Implant, Orthodontics and Complication.
Marcel Zwahlen focuses on Internal medicine, Cohort study, Logistic regression, Eosinophilic esophagitis and Surgery. His study ties his expertise on Cardiology together with the subject of Internal medicine. Marcel Zwahlen combines subjects such as Longitudinal study, Mortality rate, Marital status, Hazard ratio and Cohort with his study of Cohort study.
His Logistic regression research is multidisciplinary, relying on both Colorectal cancer, Socioeconomic status, Prospective cohort study and Public health. His work in Socioeconomic status addresses subjects such as Vaccination, which are connected to disciplines such as Confidence interval. The study of Surgery is intertwined with the study of Clinical trial in a number of ways.
His primary areas of investigation include Surgery, Internal medicine, Cohort study, Dentistry and Survival rate. Marcel Zwahlen interconnects Serology, Conventional PCI, Percutaneous coronary intervention and Confidence interval in the investigation of issues within Surgery. Marcel Zwahlen is involved in the study of Internal medicine that focuses on Survival analysis in particular.
His studies in Dentistry integrate themes in fields like Complication, Poisson regression and Implant. His Complication research is multidisciplinary, incorporating perspectives in Prospective cohort study and Incidence. His work deals with themes such as Meta-analysis and Eosinophilic esophagitis, which intersect with Prospective cohort study.
