Targeted literature searches are a fundamental part of writing clinical manuscripts that will meet the standards of high-quality journals and contribute meaningfully to evidence-based practice. When physicians write clinical manuscripts, utilizing a targeted literature search can identify high-quality, relevant, and current evidence. While a general literature review is useful, a targeted literature search is specific to the clinical question and should be completed through frameworks established, such as PICO (Population, Intervention, Comparator, Outcome) and PRISMA [1].

A properly developed research proposal and protocol play an important role in meeting scientific integrity, adherence to ethical conduct, and success in obtaining funding in academic and clinical research. A “protocol” and “proposal” are not the same. They have different purposes. A protocol is a carefully written plan of the study to be conducted, whereas a proposal is a persuasive document seeking approval or funding.

This article highlights the critical components, format, and best practices in the writing of research protocols and proposals for students, clinical researchers, and academic institutions.

1. Understanding the Purpose

Study designs are broadly categorized into observational and experimental studies. Each category includes specific subtypes suited for different types of research questions.

Document Type	Primary Purpose	Audience
Research Protocol	To ensure methodological accuracy and ethical standards	Ethics committees, IRBs
Research Proposal	To persuade stakeholders about the value and feasibility of the research	Funding agencies, supervisors

2. Key Components of a Research Protocol

A standard research protocol for academic or clinical studies is usually in a structured format with the following sections:

2.1. Title Page

Project Title (Clear, specific, and concise)
Principal Investigator (Name, affiliation, contact)
Co-Investigators (if applicable)
Institutional Affiliation
Date and Version of Protocol

Example:

The effectiveness of clinic versus home-based, artificial intelligence-guided therapy in patients with low back pain: Non-randomized clinical trial [1].

2.2. Background and Rationale

This section justifies the need for the study by highlighting current gaps in knowledge, clinical challenges, or public health issues.

Review recent literature.
Identify the knowledge gap.
Provide epidemiological/statistical support.

Example:

Chronic low back pain affects over 30% of individuals aged above 60 years, with existing treatments showing limited long-term efficacy

2.3. Objectives

Define primary and secondary objectives using specific and measurable terms.

Primary Objective: The main question the study aims to answer.
Secondary Objectives: Additional questions of interest.

Example:

Primary Objective	Secondary Objective
Investigate the effectiveness of antihypertensive drugs initiated as a two‐drug combination versus monotherapy on BP control and cardiovascular risk [2]	Assess whether the effects were similar according to the severity of hypertension, and in the patients initiating a combination of ACEi + CCB compared with those initiated with either single class [2]

2.4. Study Design

Mention the type of study:

Study Type	Description
RCT (Randomized Controlled Trial)	Intervention assigned randomly
Cohort Study	Observational, follows the group over time
Cross-sectional	Data at one point in time
Case-control	Compares past exposure in cases and controls

Include:

Study setting (e.g., outpatient clinic)
Number of groups (e.g., control/intervention)
Randomization, blinding, and allocation process

2.5. Study Population

Provide inclusion and exclusion criteria [3].

Inclusion Criteria	Exclusion Criteria
Patients above the age of 18 years	Pregnant women
Diagnosed (SARS-CoV-2 PCR positive on nasopharyngeal swab) COVID-19 with moderate to severe disease or mild disease with any co-morbidities were included in the study	Patients transferred from other hospitals directly for ICU care, and then subsequently de-escalated to the ward, and patients who died during the hospital stay

2.6. Outcome Measures

Use validated tools and clear definitions:

Primary Outcome:

Pain score using the Visual Analog Scale (VAS) after 12 weeks

Secondary Outcomes:

Quality of Life (WHOQOL-BREF)
Exercise adherence (% sessions completed)

2.7. Data Collection and Analysis

Data Collection Plan	Data Analysis Plan
Data points: baseline, 6 weeks, 12 weeks	Statistical tests: T-tests, chi-square, ANOVA
Instruments: VAS, WHOQOL-BREF, usage logs	Software: SPSS v26 or R

3. Ethical Considerations

Informed Consent: Provide template and procedure.
Confidentiality: Data storage, anonymization.
Ethics approval: Include planned submission to IRB or EC.

Example:

Before the collection of data, this study was approved by the Non-Interventional Health Research Ethics Committee of Dokuz Eylül University (Protocol no: 2023/40-16). The study was conducted per the Declaration of Helsinki [4].

5. Drafting a Research Proposal

Unlike the protocol, the proposal adds persuasive elements, including budget, impact, and feasibility.

5.1. Executive Summary

Unlike the protocol, the proposal adds persuasive elements, including budget, impact, and feasibility.

5.2. Significance and Innovation

Why is the study important?
What novel contributions will it make?
Relevance to national/global health priorities.

5.3. Methodology Overview

Briefly summarize the protocol’s design, population, and statistical approach.

6. Practical Tips for Effective Writing

Use active voice and avoid redundancy.
Avoid jargon; explain all technical terms.
Reference recent literature to support the need for the study.
Follow institutional templates where available.
Use referencing tools like Zotero or Mendeley for citation management.

7. Common Mistakes to Avoid

Vague objectives and unclear hypotheses.
Poor alignment between objectives and methods.
Ignoring feasibility or budget constraints.
Omitting ethical considerations.
Lack of proper citations or outdated references.

Conclusion

Writing a research protocol or proposal requires precision, clarity, and scientific justification. Each of the sections should logically connect, be based on evidence, and meet ethical guidelines. Using the standardized structure provides for a systematic approach to peer review, funding approval, and completing either an academic or clinical study successfully.
