Keeping up with ophthalmic research is a daunting task. Understanding the conclusion and implications, let alone the research methods and increasingly complex statistics, can be intimidating. Fortunately, however, there are many resources that can help one assimilate and synthesize research into clinical practice. Regardless of your background in epidemiology and statistics, the sections in this guide can help you make use of these resources and understand the science behind them.

Sections in This Guide
1. Evidence-Based Medicine
- Highlights the basics of evidence-based medicine and what it means to practice medicine in this manner.
- Includes a grading scale to highlight different types of evidence and how they should be implemented in practice.
2. Statistical Concepts
- Touches upon basic statistical concepts and definitions that must be mastered before one can appreciate different types of statistical analysis.
- Includes a standard definition for each concept and an ophthalmology related example from peer-reviewed literature.
3. Epidemiologic Concepts
- Highlights how to analyze study results in the context of different study designs.
- Considers limitations in study design, study conduction, and statistical analysis.
4. Study Designs
- Provides information on the different options one has in designing a study.
