Summary
Systematic literature reviews (SLRs) analyzing randomized controlled trials (RCTs) are increasingly published. Cardiovascular and endocrine diseases are the most frequently reviewed topics in these impactful evidence-based studies.
Area of Science:
- Medical research methodology
- Evidence-based medicine
- Bibliometrics
Background:
- Systematic literature reviews (SLRs) and meta-analyses are highly valued in the hierarchy of scientific evidence.
- Understanding the publication trends of SLRs is crucial for assessing research impact and focus.
Purpose of the Study:
- To evaluate the historical trends in the publication of systematic literature reviews (SLRs) that specifically analyze randomized controlled trials (RCTs).
Main Methods:
- A comprehensive search of the Medline database was conducted using a focused strategy.
- Included SLRs were coded by ICD-10, and the number of RCTs per SLR was recorded.
- Exclusion criteria included protocols, commentaries, and errata; no date restrictions were applied.
Main Results:
- A significant increase in the annual publication of SLRs of RCTs was observed over the years.
- Diseases of the circulatory system (750 studies) and endocrine, nutritional, and metabolic diseases (734 studies) were the most frequently analyzed areas.
- Most SLRs synthesized findings from 11 to 50 RCTs.
Conclusions:
- The growing number of published SLRs reflects their increasing recognition and utility in synthesizing evidence.
- The focus on prevalent diseases like circulatory and endocrine disorders aligns with global health priorities for mortality and disability.

02:20Longitudinal Research
12.0K
Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

01:26Methods of Documentation II: POMR
989
The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

01:18Introduction To Survival Analysis
277
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.
The primary goal of survival analysis is to estimate survival time—the time...

222
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...
