Which one of the following has the highest range of evidence?
Correct Answer
C. Systematic Review
Explanation
A systematic review has the highest range of evidence among the given options. It involves a comprehensive and rigorous analysis of multiple studies on a specific topic, using predefined methods to identify, select, and critically appraise relevant research. By synthesizing the findings of multiple studies, a systematic review provides a more reliable and unbiased summary of the available evidence compared to other types of reviews. This makes it a valuable tool for evidence-based decision-making in healthcare and other fields.
2.
Which one of the following has the lowest range of evidence?
Correct Answer
C. Narrative Review
Explanation
A narrative review is a type of literature review that summarizes and synthesizes existing research studies without a systematic and rigorous approach. It relies heavily on the author's interpretation and subjective analysis of the evidence, making it the lowest range of evidence among the given options. In contrast, a systematic review follows a well-defined methodology, includes a comprehensive search strategy, and critically appraises the quality of the included studies, providing a higher level of evidence.
3.
What are great advantages of Systematic reviews?
Correct Answer
D. All of above
Explanation
Systematic reviews have several advantages. They use an explicit method, which means that their process is clearly defined and transparent. This ensures that the review is conducted in a rigorous and systematic manner. Additionally, systematic reviews answer specific questions, which helps to focus the review and provide relevant and targeted information. Furthermore, systematic reviews include all relevant articles in the literature, ensuring that the review is comprehensive and unbiased. Therefore, the correct answer is "All of above."
4.
Statistical method used in the narrative review is meta-analysis
Correct Answer
B. False
Explanation
The explanation for the answer being false is that the question states that the statistical method used in the narrative review is meta-analysis. However, this statement is incorrect. Meta-analysis is not a statistical method used in a narrative review. A narrative review is a qualitative summary of the literature, whereas meta-analysis is a quantitative method that combines data from multiple studies to provide a more precise estimate of the effect of an intervention or exposure. Therefore, the correct answer is false.
5.
The summary statistics (effect size) that are usually used to measure treatment effect include
Correct Answer
E. All of above
Explanation
The summary statistics that are usually used to measure treatment effect include odds ratios (OR), relative risks (RR), risk differences, and standardized mean differences. These statistics provide different ways of quantifying the effect size and comparing the treatment effect between groups. The choice of which statistic to use depends on the type of data and the research question being addressed.
6.
The Forest Plot is (which is NOT TRUE)
Correct Answer
D. Found in all review studies
Explanation
The Forest Plot is not found in all review studies. This statement implies that the Forest Plot is a common feature in all review studies, which is not true. The Forest Plot is a graph that displays the results of a meta-analysis, showing information from individual studies. It allows for a visual assessment of the heterogeneity among studies. However, not all review studies use or include the Forest Plot in their analysis.
7.
The limitations of meta-analysis are
Correct Answer
D. All of above
Explanation
The correct answer is "All of the above." This means that all of the limitations mentioned in the question (potential bias, variation in definitions among studies, and the possibility of pooled results changing depending on factors) are applicable to meta-analysis. Meta-analysis can be subject to bias due to factors such as publication bias or selective reporting of results. Additionally, the variation in definitions used by different studies can affect the comparability and generalizability of the results. Finally, the pooled results in a meta-analysis can be influenced by various factors, such as the inclusion/exclusion criteria, study design, or statistical methods used.
8.
A systematic review can be performed without a meta-analysis and a meta-analysis can be conducted without a systematic review
Correct Answer
A. True
Explanation
This statement is true because a systematic review involves a comprehensive and structured analysis of all available research studies on a particular topic, while a meta-analysis is a statistical technique used to combine the results of multiple studies. Therefore, it is possible to conduct a systematic review without performing a meta-analysis if the studies included in the review do not lend themselves to statistical pooling. Similarly, a meta-analysis can be conducted without a systematic review if the researcher only focuses on combining and analyzing the results of existing studies without conducting a comprehensive review of the literature.
9.
This article was
Correct Answer
C. A letter
Explanation
The correct answer is "a letter" because the question is asking about the type of article, and a letter is a specific type of written communication that is typically addressed to a person or organization.

Narrative reviews are criticized because they are
Correct Answer
A. Generally biased
Explanation
Narrative reviews are criticized because they are generally biased. This means that they often include personal opinions, perspectives, or biases of the author, which can affect the objectivity and reliability of the review. Unlike systematic reviews or meta-analyses that follow a formal and rigorous methodology, narrative reviews are more subjective and prone to bias. They may not consider all available evidence or selectively cite reports that support the author's viewpoint. This lack of selectivity in citing reports can further contribute to the bias in narrative reviews.
