";s:4:"text";s:12531:"[1][2] Critical appraisal methods form a central part of the systematic review process. Relative Risk (RR) = risk of the outcome in the treatment group / risk of the outcome in the con-trol group. This is because when reading any type of evidence, being critical of all aspects of the study design, execution and reporting is vital for assessing its quality before being applied to practice.13 Systematic reviews have been used to develop guidelines and to answer important questions for evidence-based practice3 ,4 and CA to assess the quality of studies that have been included is a crucial part of this process.5 Teaching CA has become an important part of the curriculum in medical schools and plays a central role in the interpretation and dissemination of research for evidence-based practice.69.

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. Critical appraisal is much more than a 'tick box' exercise. The study compared five different algorithms to find the best model, adding to the limited research on stroke risk prediction in China. 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.
