PICO Formatting  

1. P (Patient, Population, or Problem): Describe the group of people or the problem you're  interested in. 

 Example: Adults with high blood pressure. 

2. I (Intervention): What intervention, treatment, or exposure are you interested in studying?  Example: Taking a new medication. 

3. C (Comparison): What alternative are you comparing the intervention to, if any?  Example: Compared to taking a placebo (a fake pill). 

4. O (Outcome): What are you hoping to achieve or measure with this intervention?  Example: Reduction in blood pressure levels. 

Putting it Together: 

P: Adults with high blood pressure

I: Taking a new medication 

C: Compared to taking a placebo 

O: Reduction in blood pressure levels 

Formatted PICO Question:  

In adults with high blood pressure, does taking a new medication compared to taking a placebo  result in a reduction in blood pressure levels. 

Methodology & How to Recognize It  

Methodology refers to the analysis of the methods applied to a field of study. It is made up of the  concepts, theories, and principles that guide the research process and dictate how data is collected,  analyzed, and interpreted.  

Essentially, the methodology is the overarching strategy and methods behind the research project,  explaining why specific methods are used and how they help address the research questions or  hypotheses. 

How to Recognize Research Methodology  

To identify the research methodology in a study, look for sections that discuss the following: 

1. Theoretical Framework: The theories or concepts that underpin the research. 

2. Research Design: The overall strategy or blueprint of the research, explaining whether it is  qualitative, quantitative, or a combination of methods. 

3. Data Collection Methods: The techniques or instruments used to gather data (e.g., surveys,  interviews, observations, experiments). 

4. Sampling Methods: The process by which participants or data sources are selected (simple  random sampling, stratified sampling, cluster sampling, etc.). 

5. Data Analysis Procedures: The methods used to process, analyze and interpret the collected data. 

6. Ethical Considerations: Any ethical issues addressed during the research, such as informed  consent and confidentiality. 

7. Limitations: Potential limitations or biases in the methodology that could impact the study's  findings.  

What is RCT?  

Randomized Controlled Trial (RCT): A type of scientific study where people are randomly assigned to  one of two or more groups to test the effects of a treatment, intervention, or drug. 

How to Recognize an RCT: 

1. Random Assignment: Look for information on how participants were assigned to separate  groups. In an RCT, this assignment is done randomly, like flipping a coin, to ensure each  participant has an equal chance of being in any group. 

2. Control Group: Check if there is a control group that receives either a placebo (fake  treatment) or standard treatment for comparison. This helps researchers see if the treatment  being tested makes a difference. 

3. Blinding: See if the study mentions blinding, where participants or researchers do not know  which group they are in. Blinding helps prevent bias in how the treatment is given or how  outcomes are measured. 

4. Comparison of Outcomes: Look at how outcomes are measured and compared between  groups. In RCT, researchers typically compare outcomes between the treatment group and  the control group to see if the treatment has an effect. 

Summary:  

Randomized Controlled Trial (RCT): A study where people are randomly assigned to different groups  to test the effects of a treatment. 

Recognizing an RCT: Look for random assignment, a control group, blinding, and comparison of  outcomes when evaluating evidence. 

Quantitative vs Qualitative Research  

Quantitative Research  

• What it is: Research that focuses on numbers and measurable data. 

• What it’s for: To find patterns, test theories, and make predictions by collecting numerical  data. 

• How it works: Uses structured methods like surveys, experiments, and statistical analysis. 

• Example: Measuring the effect of a new drug on blood pressure by comparing readings  before and after treatment in a large group of patients. 

Qualitative Research  

• What it is: Research that focuses on understanding people's experiences, thoughts, and  feelings. 

• What it’s for: To explore and understand complex issues and human behavior by collecting  non-numerical data. 

• How it works: Uses open-ended methods like interviews, focus groups, and observations. 

• Example: Interviewing patients to understand their experiences and feelings about living with  chronic pain. 

Summary  

Quantitative Research: Uses numbers and statistics to test hypotheses and look for patterns. 

Qualitative Research: Uses words and stories to explore and understand deeper meanings and  experiences.

Cross-Sectional, Cohort, and Case-Control Designs  

Cross-Sectional Design  

• What it is: A study that looks at data from a population at one specific point in time. 

• What it’s for: To find out what is happening in a particular group at a particular time. 

• Example: A survey measuring the prevalence of diabetes among adults in a city. 

Cohort Design  

• What it is: A study that follows a group of people (a cohort) over time to see how certain  factors affect outcomes. 

• What it’s for: To see how certain exposures or characteristics influence the development of  outcomes over time. 

• Example: Following a group of people who exercise regularly and a group who do not over 10  years to compare their rates of heart disease. 

Case-Control Design  

• What it is: A study that compares people with a certain condition (cases) to people without  that condition (controls) to see what factors might have caused the condition. 

• What it’s for: To identify and examine factors that might be associated with the condition. 

• Example: Comparing people with lung cancer (cases) to people without lung cancer (controls)  to see if there are differences in their smoking history. 

Summary  

• Cross-Sectional: Looks at a snapshot of a population at one point in time to understand what  is currently happening. 

• Cohort: Follows groups over time to see how certain factors influence outcomes. • Case-Control: Compares people with a condition to those without identifying possible causes  or risk factors. 

Levels of Analysis 

Understanding LOEs helps researchers and clinicians determine the reliability and strength of  evidence when making decisions about treatments or interventions. 

Level I  

What it is: The highest level of evidence.  

Criteria: More than one well-designed randomized controlled trial (RCTs).

Criteria: Systematic review or report of at least one Level I study. 

Level III:  

What it is: Moderate-Quality Evidence. 

Criteria: Controlled trials without randomization.  

Case-control studies. 

Still well-designed. 

Level IV  

What it is: Lower Moderate-Quality evidence 

Criteria: Evidence directly from observational studies such as cohort, case-control, or cross sectional studies.  

Level V:  

What it is: Low-quality Evidence 

Criteria: Evidence from multiple reviews or reports of cohort, case-control, or cross-sectional  studies.  

Level VI:  

What it is: Lower-Quality Evidence 

Criteria: Evidence from a single study that uses non-measurable research methods. 

Level VII:  

What it is: Lowest-Quality Evidence

Criteria: Expert opinions; expert is qualified, but no studies are presented to support evidence.
