Overview

What is he best known for?

The fields of study he is best known for:

  • Cancer
  • Internal medicine
  • Disease

Christoffer Johansen spends much of his time researching Cancer, Risk factor, Cohort study, Epidemiology and Internal medicine. The concepts of his Cancer study are interwoven with issues in Psychiatry, Depression and Incidence. His research integrates issues of Odds ratio, Surgery, Relative risk, Case-control study and Pediatrics in his study of Risk factor.

His study in Cohort study is interdisciplinary in nature, drawing from both Absolute risk reduction, Gerontology, Retrospective cohort study, Socioeconomic status and Cohort. The Epidemiology study which covers Confidence interval that intersects with Poisson regression. His work carried out in the field of Internal medicine brings together such families of science as Gastroenterology and Oncology.

His most cited work include:

  • Prevalence of depression, anxiety, and adjustment disorder in oncological, haematological, and palliative-care settings: a meta-analysis of 94 interview-based studies (1175 citations)
  • Detectable clonal mosaicism and its relationship to aging and cancer (393 citations)
  • Use of selective serotonin reuptake inhibitors and risk of upper gastrointestinal tract bleeding: a population-based cohort study. (323 citations)

What are the main themes of his work throughout his whole career to date?

Internal medicine, Cancer, Cohort study, Breast cancer and Oncology are his primary areas of study. The Internal medicine study combines topics in areas such as Surgery and Glioma. The various areas that Christoffer Johansen examines in his Glioma study include Genome-wide association study and Single-nucleotide polymorphism.

The study incorporates disciplines such as Physical therapy, Incidence, Pediatrics and Risk factor in addition to Cancer. Christoffer Johansen has researched Cohort study in several fields, including Epidemiology, Psychiatry, Confidence interval, Prospective cohort study and Cohort. His research investigates the connection between Breast cancer and topics such as Randomized controlled trial that intersect with problems in Intervention.

He most often published in these fields:

  • Internal medicine (31.71%)
  • Cancer (31.41%)
  • Cohort study (20.03%)

What were the highlights of his more recent work (between 2019-2021)?

  • Internal medicine (31.71%)
  • Cancer (31.41%)
  • Depression (7.74%)

In recent papers he was focusing on the following fields of study:

His main research concerns Internal medicine, Cancer, Depression, Anxiety and Cohort study. Many of his studies involve connections with topics such as Oncology and Internal medicine. His work on Cancer survivor is typically connected to Call to action as part of general Cancer study, connecting several disciplines of science.

His Depression research is multidisciplinary, relying on both Intervention, Breast cancer, Randomized controlled trial and Clinical psychology. Christoffer Johansen usually deals with Anxiety and limits it to topics linked to Pediatrics and Neurofibromatosis, Psychosocial, Lymphoma and Hodgkin lymphoma. His study looks at the intersection of Cohort study and topics like Hazard ratio with Cohort and Obstetrics.

Between 2019 and 2021, his most popular works were:

  • Germline elongator mutations in Sonic Hedgehog medulloblastoma (24 citations)
  • Management of Cancer and Health After the Clinic Visit: A Call to Action for Self-Management in Cancer Care (11 citations)
  • Rationale and Design of the Hamburg City Health Study (8 citations)

In his most recent research, the most cited papers focused on:

  • Cancer
  • Internal medicine
  • Disease

Christoffer Johansen focuses on Cancer, Cohort study, Psychosocial, Quality of life and Pediatrics. His Cancer research includes themes of Nursing and Logistic regression. His study with Cohort study involves better knowledge in Internal medicine.

His Psychosocial research incorporates elements of Disease severity, Gerontology, Quality of life, Response rate and Depression. His Quality of life research integrates issues from Bladder cancer, Adverse effect, Standard treatment and Anxiety. His study looks at the relationship between Pediatrics and fields such as Neurofibromatosis, as well as how they intersect with chemical problems.
