“…Then, the included studies were assigned to the suitable level of efficacy. In the meantime, the review question was designed according to the PICO (Population, or Problem, Intervention or Exposure, Comparison, Outcome) element [40]. Finally, each study was evaluated for quality using the predetermined tool for quality assessment (QUADAS 2).…”

Objectives The aim of this study was to address the diagnostic efficacy of cone beam computed tomographic (CBCT) imaging in periodontics based on a systematic search and analysis of the literature using the hierarchical efficacy model. Methods A systematic search of the electronic databases such as PubMed, Scopus, Web of Science, and Cochrane was conducted until February 2019 to identify studies addressing the efficacy of CBCT imaging in Periodontics. The identified studies were subjected to pre-identified inclusion criteria followed by an analysis using a hierarchical model of efficacy (model) designed for an appraisal of the literature on a diagnostic imaging modality. Two examiners performed the eligibility and quality assessment of relevant studies, and consensus was reached where disagreement was found.Results The search resulted in 64 studies. Of these, 35 publications were allocated to the relevant level of efficacy and quality assessments wherever applicable. The overall diagnostic accuracy studies showed the risk of bias and applicability concerns in the use of CBCT to be low to moderate. In addition, CBCT is accurate in identifying periodontal defects when compared to other modalities. The studies on the level of patient outcomes agreed that CBCT is a reliable tool for the assessment of the outcomes after the treatment of periodontal defects. Conclusion CBCT was found to be beneficial and accurate in cases of infra-bony defects and furcation involvements.

“…[33] addressed the accuracy of the CBCT as a tool for the measurement of alveolar bone loss in periodontal defects. However, the authors did not report that they followed PICO, which is a framework for review question formulation [40]. In terms of a comprehensive search strategy, we saw that this review did not fulfill the criteria regarding study registries and expert consultation in the field.…”

“…In these rehabilitation research examples, we will frame questions using PICO (population, interventions, comparator, outcomes—see previous feature), then take the next steps of asking, What is the within‐group summary measure ? In other words, how did the authors summarize occurrence of the outcome in each group? What is the measure of effect ?…”

“…In a previous feature, we discussed independent and dependent variables and their EBP synonyms, interventions (or exposures), and outcomes. 3 Another way to classify variables is by their measurement scale, which describes the types of values a variable can take on and over what range. 6 Three measurement scales encompass many rehabilitation outcomes: event-type outcomes, binary variables, and continuous variables.…”
