Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Surgery
  • Disease

His primary areas of investigation include Randomized controlled trial, Clinical trial, Meta-analysis, Internal medicine and Surgery. Thomas C. Chalmers has researched Randomized controlled trial in several fields, including MEDLINE, Intensive care medicine, Physical therapy, Side effect and Statistical significance. His Clinical trial research is multidisciplinary, relying on both Cirrhosis, Sample size determination, Data extraction and Confidence interval.

His Meta-analysis research incorporates themes from Statistics, Econometrics, Protocol and Environmental health. His Internal medicine study integrates concerns from other disciplines, such as Gastroenterology and Nephropathy. His studies in Surgery integrate themes in fields like Odds ratio, Cancer pain, Diarrhea and Cardiology.

His most cited work include:

  • Effect of coronary artery bypass graft surgery on survival: overview of 10-year results from randomised trials by the Coronary Artery Bypass Graft Surgery Trialists Collaboration. (1702 citations)
  • The importance of beta, the type II error and sample size in the design and interpretation of the randomized control trial. Survey of 71 "negative" trials. (1361 citations)
  • A comparison of results of meta-analyses of randomized control trials and recommendations of clinical experts. Treatments for myocardial infarction. (1212 citations)

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

Thomas C. Chalmers focuses on Internal medicine, Randomized controlled trial, Surgery, Clinical trial and Meta-analysis. The concepts of his Internal medicine study are interwoven with issues in Gastroenterology and Endocrinology. His biological study spans a wide range of topics, including Anesthesia, MEDLINE, Research design, Pharmacotherapy and Physical therapy.

His Surgery research incorporates elements of Rheumatoid arthritis and Portacaval shunt. His work deals with themes such as Sample size determination and Confidence interval, which intersect with Clinical trial. His Meta-analysis research focuses on Statistics and how it relates to Random effects model.

He most often published in these fields:

  • Internal medicine (39.46%)
  • Randomized controlled trial (33.51%)
  • Surgery (27.57%)

What were the highlights of his more recent work (between 1994-2007)?

  • Internal medicine (39.46%)
  • Meta-analysis (22.16%)
  • Randomized controlled trial (33.51%)

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

Thomas C. Chalmers spends much of his time researching Internal medicine, Meta-analysis, Randomized controlled trial, Clinical trial and Surgery. His Internal medicine research is multidisciplinary, incorporating elements of Gastroenterology and Research design. His Meta-analysis research integrates issues from Physical therapy, Absolute risk reduction, Psychiatry and Statistical power.

His Randomized controlled trial research is multidisciplinary, incorporating perspectives in Omeprazole, Anxiety disorder, Helicobacter pylori and Amoxicillin. His research in Clinical trial intersects with topics in Statistics, Sample size determination, Data extraction, Publication bias and Protocol. When carried out as part of a general Surgery research project, his work on Randomization, Radiography and Ileostomy is frequently linked to work in Kock pouch, therefore connecting diverse disciplines of study.

Between 1994 and 2007, his most popular works were:

  • The comparative effects of postoperative analgesic therapies on pulmonary outcome : Cumulative meta-analyses of randomized, controlled trials (882 citations)
  • The Comparative Effects of Postoperative Analgesic Therapies on Pulmonary Outcome (636 citations)
  • The Effect of Dietary Protein Restriction on the Progression of Diabetic and Nondiabetic Renal Diseases: A Meta-Analysis (562 citations)

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

  • Internal medicine
  • Surgery
  • Disease

His primary scientific interests are in Meta-analysis, Anesthesia, Pulmonary function testing, Local anesthetic and Clinical trial. His research integrates issues of Anxiety disorder, Physical therapy and Randomized controlled trial, Surgery in his study of Meta-analysis. Particularly relevant to Blinding is his body of work in Randomized controlled trial.

His Anesthesia study incorporates themes from Lumbar and Lung. Thomas C. Chalmers has researched Clinical trial in several fields, including Zidovudine, Statistics, Publication bias, Protocol and Random effects model. His Relative risk research focuses on Endocrinology and how it connects with Internal medicine and Crossover study.
