The pieces in this section will focus on incorporating various types of evidence into your paper, but the main idea to keep in the back of your head is that research is much larger than your paper. Your writing is a part of a larger conversation.
The paper’s use of systemic reviews provides level l evidence to support its conclusion (Richardson-Tench et al. 2011, pp 10-12). The systemic reviews and meta-analysis studies focused on compared various different dressings, and their affects and a variation of different wounds.
Level 1A, 1B, 2A, 2B, 3A, or 3B study will provide stronger evidence than results from a Level 4 or 5 study. The Levels of Evidence are presented in Table 1 (p. 4); in addition, the evidence within a theme should be described according to the strength of the evidence (level of certainty); see Table 2 (p. 4).
The following image represents the hierarchy of evidence provided by the National Health and Medical Research Council (NHMRC). 1 Most experts agree that the higher up the hierarchy the study design is positioned, the more rigorous the methodology and hence the more likely it is that the study design can minimise the effect of bias on the results of the study.
Levels of evidence.. Therefore, systematic reviews always consider the quality of evidence in each research study before summarizing the information in a review. Some terms that you may see in a systematic review are the 'strength of the evidence' and the 'size of the effect'.. The second level of evidence is provided by at least one.
The addition of level of evidence ratings to the journal has several benefits: improve studies by an explicit delineation of the primary research question; allow monitoring and reporting of trends.
