Was the sample frame taken from an appropriate population base so that it closely represented the target/reference population under investigation? Thus, this cross-sectional study was designed to assess the prevalence of MMC in M1M using CBCT images and investigate the effect of some demographic factors on its prevalence. retrospective studies are case series and cross sectional studies, while analytical retrospective studies are cross sectional, case control and cohort studies. Objectives To evaluate the risk of bias tool, introduced by the Cochrane Collaboration for assessing the internal validity of randomised trials, for inter-rater agreement, concurrent validity compared with the Jadad scale and Schulz approach to allocation concealment, and the relation between risk of bias and effect estimates. In case of disagreement, another author was consulted, and discussions were held until a consensus was reached. Traditionally, evidence-based practice has been about using systematic reviews of randomised controlled trials (RCTs) to inform the use of interventions.10 However, other types/designs of research studies are becoming increasingly important in evidence-based practice, such as diagnostic testing, risk factors for disease and prevalence studies,10 hence systematic reviews in this area have become necessary. Critical appraisal aims to identify potential threats to the validity of the research findings from the literature and provide consumers of research evidence the opportunity to make informed decisions about the quality of research evidence. Of those that took part, 8 were involved in clinical, teaching and research duties and 10 were involved in research and teaching, 5 of the participants were veterinary surgeons and 6 were medical clinicians. This is a 20-item appraisal tool developed in response to the increase in cross-sectional studies informing evidence-based medicine and the consequent importance of ensuring that these studies are of high quality and low bias25.

The interests and experiences of the panel will clearly have had an effect on the results of this study as this is common to all Delphi studies.31 ,41 The majority of Delphi studies are conducted using between 15 and 20 participants,31 so a panel of 18 is consistent with other published Delphi panels. Relative Risk (RR) = risk of the outcome in the treatment group / risk of the outcome in the con-trol group. Using a similar process to other appraisal tools,37 we reviewed the relevant literature to develop a concise background on CA of CSSs and to ensure no other relevant tools existed. If consensus was 50%, components were removed from the tool. Critical appraisal worksheets to help you appraise the reliability, importance and applicability of clinical evidence. they held a postgraduate qualification (eg, PhD, MSc, European College Diploma in Veterinary Public Health); they were recognised through publication and/or key note presentations for their work in EBM and veterinary medicine, epidemiology or public health; had authored in systematic reviews (in medicine or veterinary medicine), reporting guidelines or CA. By t = 1.5 (label (d) in Figure 2 ), the laminar core of the CFR breaks down and the color map no longer detects an axis. Fundamentally, the tool developed by Berra et al15 only appraises the quality of reporting of CSSs and does not address risk of bias or other aspects of study quality.16 Good quality of reporting of a study means that all aspects of the methods and the results are presented well and in line with international standards such as STROBE;17 however, this is only one aspect of appraisal as a well-reported study does not necessarily mean that the study is of high quality. CA of the literature is a vital step in evidence synthesis and therefore evidence-based decision-making in a number of different disciplines.
