Scholarly Article Types

Original Research

These articles are written by the researchers who performed the actual study in the lab or in another setting. They typically include methods, results, and discussion sections related to a single research project. These articles are considered primary sources.

Case Study

A detailed analysis of an individual or group as a model for a particular medical phenomena. These articles' impact is limited due to sample size, but they can serve as a starting point for more in-depth research.

Review

An article that summarizes and synthesizes the findings of numerous original research articles. Reviews are heavily used by researchers who wish to keep up with the literature on a topic. These articles can be used to identify original research (i.e., primary sources) for further reading. Reviews are considered secondary sources.

Systematic Review

These types of studies employ a systematic method to analyze and synthesize the results of numerous studies. Systematic reviews are widely used in the health sciences, often to find a generalized conclusion from multiple evidence-based studies (e.g., "85% of the studies showed a positive correlation with..."). 

Meta-Analysis

A systematic method that uses statistics to analyze the data from numerous studies. The researcher will combine the actual data from studies with similar data types (i.e., males between 25-30 years old with vitamin D deficiency) and analyze them as a single expanded data set. PubMed treats meta-analysis as a subset of systematic reviews.
