Conclusion statements were developed regarding the evidence within each clinical question, and a level of confidence in the evidence was assigned to each conclusion using a modified GRADE methodology.
A level of evidence was assigned to each identified article by five internists using the Newcastle Ottawa Scale for follow-up, cohort, case-series and case-control studies, the CC's risk of bias tool for trials and the Cochrane Effective Practice and Organisation of Care Group risk of bias criteria for before and after trials.
Third, the distances between evidence and clusters centroids are calculated and evidence are assigned to the nearest cluster, as shown in Fig. 12.
After abstraction of information, a level of evidence was assigned to the outcomes of each study.
For example, in the case of protein DNA interactions, strong evidence is assigned to experiments that directly show such interactions, as footprinting (FP) with purified proteins, while weak evidence is assigned to gel mobility shift assays using cell extracts, computational predictions or author statements.
For both quantitative and qualitative data synthesis, a level of evidence was assigned to each outcome according to the recommendations proposed by van Tulder et al. 48 The electronic search identified 5269 records and following removal of duplicates, the titles and abstracts of 2251 articles were screened.
Thus if a participant reported using any product lacking levels A or B evidence support (e.g., bromelain and MSM which have level C or lower evidence support), they were assigned to the "low" scientific evidence category.
Therefore, no studies were assigned to evidence level I, II or III.
Evidence grades and clinical recommendation scores were assigned to each prophylactic drug based on published evidence.
Based on these evidences, rats in this study were assigned to the three exercise groups and received their prescribed rehabilitation intervention for seven consecutive days (I1-I7), while Con rats were put in standard cage and allowed spontaneous recovery after stroke.
