To perform a thorough assessment of the recently published Mint Trials in order to illustrate how to read and analyze a study critically, according to principles of evidence-based medicine.
Narrative review.
We have applied the recently published guidelines for composing and assessing studies on the treatment of pain to a recently published article describing a large study that claimed its "findings do not support the use of radiofrequency denervation to treat chronic low back pain." These guidelines describe the critical components of a high-quality manuscript that allows communication of all relevant information from authors to readers.
Application of evidence-based medicine principles to the publication describing the Mint Trials reveals significant issues with the methodology and conclusions drawn by the authors. A thorough assessment demonstrates issues with inclusion/exclusion criteria, diagnostic block protocols, radiofrequency neurotomy technique, co-interventions, outcome measurement, power analysis, study sample characteristics, data analysis, and loss to follow-up. A failure to definitively establish a diagnosis, combined with use of an inadequate technique for radiofrequency neurotomy and numerous other methodological flaws, leaves the reader unable to draw meaningful conclusions from the study data.
Critical analysis, rooted in principles of evidence-based medicine, must be employed by writers and readers alike in order to encourage transparency and ensure that appropriate conclusions are drawn from study data.
根据循证医学原则,对最近发表的 Mint 试验进行全面评估,说明如何批判性地阅读和分析研究。
叙述性综述。
我们将最近发表的关于疼痛治疗研究的组成和评估指南应用于最近发表的一篇描述一项大型研究的文章,该研究声称其“研究结果不支持使用射频神经阻断术治疗慢性下腰痛”。这些指南描述了高质量手稿的关键组成部分,使作者与读者能够交流所有相关信息。
将循证医学原则应用于描述 Mint 试验的出版物揭示了作者在方法和结论方面存在的重大问题。彻底的评估显示出纳入/排除标准、诊断阻滞方案、射频神经切断术技术、联合干预、结果测量、功效分析、研究样本特征、数据分析和随访丢失等方面的问题。未能明确确定诊断,加上射频神经切断术技术的不充分应用以及其他许多方法学缺陷,使得读者无法从研究数据中得出有意义的结论。
批判性分析,根植于循证医学原则,必须得到作者和读者的共同运用,以鼓励透明度并确保从研究数据中得出适当的结论。
