  • Internal medicine (52.88%)
  • Cardiology (33.70%)

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

Richard M. Allman mainly focuses on Heart failure, Internal medicine, Cardiology, Hazard ratio and Confidence interval. Richard M. Allman combines subjects such as All cause mortality, Lower risk, Emergency medicine, Intensive care medicine and Propensity score matching with his study of Heart failure. Ejection fraction, Digoxin, Older patients, Prospective cohort study and Comorbidity are among the areas of Internal medicine where Richard M. Allman concentrates his study.

His work on Heart failure with preserved ejection fraction as part of general Cardiology study is frequently linked to In patient, bridging the gap between disciplines. Richard M. Allman focuses mostly in the field of Hazard ratio, narrowing it down to topics relating to Pediatrics and, in certain cases, Multiple Chronic Conditions, Kidney disease, Increased risk, Retrospective cohort study and Healthcare utilization. His Confidence interval research is multidisciplinary, relying on both Randomized controlled trial, Demography, Ambulatory, Cohort and Risk factor.

Between 2016 and 2021, his most popular works were:

  • Life-Space Mobility Change Predicts 6-Month Mortality (31 citations)
  • Human neuromuscular aging: Sex differences revealed at the myocellular level. (23 citations)
  • Association of Multimorbidity with Mortality and Healthcare Utilization in Chronic Kidney Disease. (23 citations)

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

  • Internal medicine
  • Disease
  • Surgery

Richard M. Allman spends much of his time researching Heart failure, Internal medicine, Hazard ratio, Cardiology and Confidence interval. In his study, Intensive care medicine, Discharge home and Heart rate is inextricably linked to Lower risk, which falls within the broad field of Heart failure. He works on Internal medicine which deals in particular with Ejection fraction.

His work carried out in the field of Hazard ratio brings together such families of science as Renal function, Increased risk, Retrospective cohort study, Healthcare utilization and Pediatrics. His study looks at the relationship between Cardiology and fields such as Blood pressure, as well as how they intersect with chemical problems. His work in Confidence interval tackles topics such as Propensity score matching which are related to areas like Ambulatory, Digoxin, Referral, Emergency medicine and Health services.
