1. An Academic presentation by Dr. Nancy Agnes, Head, Technical Operations, Pubrica Group: www.pubrica.com Email: sales@pubrica.com How to conduct a systematic review for prospective studies?

2. The purpose of thissystematic review is to consolidate and critically assess the findings of prospective research from many fields. • Prospective studies can provide important information on cause-and-effect associations, risk factors, and prognostic variables. • A thorough search of electronic resources and manual assessment of references discovered prospective studies fulfilling the inclusion criteria. • This blog gives a thorough review of performing prospective studies as well as recommends interesting areas for additional research.

3. INTRODUCTION • A systematic review of prospective studiesinvolves a rigorous and structured approach to identifying, appraising, and synthesizing all the relevant research on a specific topic. • Here is a step-by-step guide on how to conduct a systematic review of prospective studies: contd...

4. Define the research question: Start by developing a clear and focused research question, specifying the population, intervention or exposure, comparator, and outcome (PICO) elements. Develop a protocol: Before starting the review process, create a protocol that outlines the objectives, inclusion and exclusion criteria, search strategy, data extraction process, and methods for assessing study quality and synthesizing findings. contd...

5. Perform a comprehensive literature search: • Conduct a thorough search of relevant databases (e.g., PubMed, Embase, Web of Science) using appropriate keywords and search terms. • Additionally, check reference lists of included studies and relevant reviews for potentially eligible studies. • Screen and select studies: • Screen the titles and abstracts of the identified articles for eligibility according to the pre-defined inclusion and exclusion criteria. • Obtain the full text of potentially eligible articles and perform a more detailed assessment to determine their suitability for inclusion in the review.

7. Data extraction: • Extract relevant data from the included studies using a standardized data extraction form. • This may include study design, population characteristics, sample size, intervention or exposure details, outcome measures, and results. • Assess the quality of the included studies: • Evaluate the quality and risk of bias of the included prospective studies using an appropriate appraisal tool (e.g., the Newcastle-Ottawa Scale for cohort studies or the Cochrane Risk of Bias tool for randomized controlled trials). • This step helps ensure that the review findings are based on high-quality evidence.

8. Synthesize the findings: • Depending on the included studies' nature and heterogeneity, you may perform a meta-analysis to quantitatively combine the results or conduct a narrative synthesis to describe the findings qualitatively. • In both cases, report the main results, including effect estimates and measures of uncertainty (e.g., confidence intervals). • Interpret the results and draw conclusions: • Discuss the review's main findings in the context of the existing literature, considering the strength and limitations of the evidence. • Provide recommendations for clinical practice or policy and suggestions for future research.

9. Report the review: • Write a clear, concise, and well-structured report of the systematic review, following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to ensure transparency and completeness. • Update the review: • Systematic reviews may need to be updated periodically as new research becomes available. • Keep track of new evidence and consider updating the review if significant findings emerge that might change the conclusions.

Research question and objectives • Systematic review research questions should be practical, intriguing, new, ethical, and relevant. PICO (Population, Intervention, Comparison, Outcome) and SPIDER (Sample, Phenomenon of Interest, Design, Evaluation, Research type) are two often utilized tools. • PICO is utilized for quantitative evidence synthesis and is more sensitive than the specialized SPIDER technique. • SPIDER is recommended for qualitative and mixed techniques searches. A hybrid strategy employing both methods is advised for extensive searches, especially when applying qualitative research to qualitative issues.

Inclusion and exclusion criteria • The PICO technique, research design, and date are used to determine eligibility. The most common exclusion criteria include irrelevant, duplicated, unavailable full texts, or abstract-only studies. • These exclusions should be communicated in advance to avoid bias in the researcher. Articles containing the target patients, researched interventions, or a comparison of two studied therapies would be the inclusion criteria. • In a nutshell, it would be publications that include information that answers our study topic. The most significant aspect is that there should be clear and adequate positive and negative information to answer the question.
