Abstract
The minimal clinically important difference (MCID) is a threshold above which a score change would represent a change in symptoms that is noticeable by patients, and it has become a standard approach in the interpretation of clinical relevance of changes in PROMs at a population level. Given the lack of a methodological gold standard, high variability is the main limitation of MCID. Reporting both anchor and distribution-based MCID estimates is a strategy that guarantees both patient-perceived clinical relevance and statistical significance.
期刊介绍：
Clinical Spine Surgery is the ideal journal for the busy practicing spine surgeon or trainee, as it is the only journal necessary to keep up to date with new clinical research and surgical techniques. Readers get to watch leaders in the field debate controversial topics in a new controversies section, and gain access to evidence-based reviews of important pathologies in the systematic reviews section. The journal features a surgical technique complete with a video, and a tips and tricks section that allows surgeons to review the important steps prior to a complex procedure.
Clinical Spine Surgery provides readers with primary research studies, specifically level 1, 2 and 3 studies, ensuring that articles that may actually change a surgeon’s practice will be read and published. Each issue includes a brief article that will help a surgeon better understand the business of healthcare, as well as an article that will help a surgeon understand how to interpret increasingly complex research methodology. Clinical Spine Surgery is your single source for up-to-date, evidence-based recommendations for spine care.
