Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Disease
  • Surgery

His primary areas of study are Internal medicine, Medical prescription, Drug, Odds ratio and Epidemiology. As part of his studies on Internal medicine, Jesper Hallas often connects relevant subjects like Surgery. His Medical prescription research is multidisciplinary, incorporating elements of Pediatrics and Family medicine.

His studies in Drug integrate themes in fields like Polypharmacy, Odds and Medical emergency. His research in Odds ratio intersects with topics in Anesthesia, Antithrombotic, Case-control study, Upper gastrointestinal bleeding and Clopidogrel. His study explores the link between Epidemiology and topics such as Intensive care medicine that cross with problems in Pharmacotherapy and Prescription database.

His most cited work include:

  • The Danish National Prescription Registry (1249 citations)
  • The Danish prescription registries. (534 citations)
  • Data Resource Profile: The Danish National Prescription Registry. (355 citations)

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

His main research concerns Internal medicine, Medical prescription, Odds ratio, Cohort study and Confidence interval. His Internal medicine research incorporates themes from Gastroenterology and Surgery. Jesper Hallas has included themes like Epidemiology, Pediatrics and Drug in his Medical prescription study.

His Drug study is associated with Pharmacology. Jesper Hallas has researched Odds ratio in several fields, including Confounding and Risk factor. His Cohort study research includes elements of Relative risk, Propensity score matching, Retrospective cohort study and Cohort.

He most often published in these fields:

  • Internal medicine (63.26%)
  • Medical prescription (26.85%)
  • Odds ratio (20.47%)

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

  • Internal medicine (63.26%)
  • Cohort study (18.29%)
  • Odds ratio (20.47%)

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

Internal medicine, Cohort study, Odds ratio, Confidence interval and Medical prescription are his primary areas of study. Gout is closely connected to Active Comparator in his research, which is encompassed under the umbrella topic of Internal medicine. His work in Cohort study covers topics such as Absolute risk reduction which are related to areas like Patient centred, Number needed to treat and Intensive care medicine.

His Odds ratio study integrates concerns from other disciplines, such as Interquartile range, Vitamin K antagonist, Disease, Cohort and Comorbidity. His work deals with themes such as Observational study, Confounding and Risk factor, which intersect with Confidence interval. Jesper Hallas is involved in the study of Medical prescription that focuses on Pharmacoepidemiology in particular.

Between 2019 and 2021, his most popular works were:

  • Characteristics and predictors of hospitalization and death in the first 11 122 cases with a positive RT-PCR test for SARS-CoV-2 in Denmark: a nationwide cohort. (58 citations)
  • Characteristics and predictors of hospitalization and death in the first 11 122 cases with a positive RT-PCR test for SARS-CoV-2 in Denmark: a nationwide cohort. (58 citations)
  • Adverse outcomes and mortality in users of non-steroidal anti-inflammatory drugs who tested positive for SARS-CoV-2: A Danish nationwide cohort study. (20 citations)

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

  • Internal medicine
  • Disease
  • Cancer

His primary scientific interests are in Internal medicine, Odds ratio, Cohort, Cohort study and Epidemiology. His study in Intensive care unit, Atrial fibrillation, Confidence interval, Hazard ratio and Disease are all subfields of Internal medicine. In Odds ratio, he works on issues like Case-control study, which are connected to Crossover study, Gastroenterology, Acute pancreatitis and Bladder cancer.

His Cohort study also includes

  • Kidney disease which connect with Cause of death, Heart failure, Comorbidity and Stroke,
  • Young adult, Incidence, Pediatrics and Vaccination most often made with reference to Adverse effect. His research investigates the link between Cohort study and topics such as Relative risk that cross with problems in Absolute risk reduction and Renal replacement therapy. His study in Absolute risk reduction is interdisciplinary in nature, drawing from both Medical prescription, Prescription drug, Propensity score matching and Emergency medicine.
