文题释义:
受试者工作曲线下面积:ROC(Receiver Operating Characteristic)曲线,也就是受试者工作特征曲线,用于二分类判别效果的分析与评价。一般自变量为连续变量,因变量为二分类变量。基本原理是通过判断点(cutoff point/cutoff value)的移动,获得多对灵敏度(sensitivity)和误判率[1-Specificity(特异度)],以灵敏度为纵轴,以误判率为横轴,连接各点绘制曲线,然后计算曲线下的面积,面积越大,判断价值越高。
发表偏倚:是临床医学文献一个广为人知的现象。阳性的研究结果发表的机会更多,发表的速度更快,所发表刊物的影响因子更高。获得发表的研究是获取结论的主要依据,因此,过分强调阳性结果可能造成误导。相对于那些带有故意伪造数据的发表文章,被筛选掉的未发表研究可能更普遍,并更有可能对患者产生不利的后果。因此对是否存在阳性结果可得到优先发表的发表偏倚进行调查。
 
摘要
背景:骨关节感染因骨特有的解剖生理特征,其治疗成功率仍不理想。成功治疗的关键在于早期诊断,因此寻求一个敏感度与特异度均较高的生物学标志物十分必要。
目的:系统评价降钙素原对成人骨关节感染的诊断价值。
方法:计算机检索1990年至2017年6月Pubmed、Embase、The Cochrane library及中国知网、中国生物医学文献数据库、万方数据库发表的文献。由2位评价员按照预先设定的纳入与排除标准独立筛选文献、提取资料,利用诊断试验质量评价工具2评价纳入研究的偏倚风险后,采用Stata 14.0 软件进行Meta分析,计算合并敏感度、特异度、阳性似然比、阴性似然比、诊断比值比,绘制受试者工作特征曲线并计算曲线下面积。
结果与结论:①共纳入10篇文献,包含893例患者;②降钙素原诊断成人骨关节炎的合并敏感度、特异度、阳性似然比、阴性似然比、诊断比值比分别为0.82(95%CI=0.72-0.89)、0.89(95%CI=0.82-0.93)、7.20(95%CI=4.6-11.3)、0.20(95%CI=0.13-0.32)、35(95%CI=18-71)和0.92(95%CI=0.90-0.94);③综上,降钙素原在诊断成人骨关节炎中具有较高的诊断效能。

Abstract:

BACKGROUND: Due to special physiological characteristics, articular infection is difficult to be cured successfully. Early diagnosis is critical for the treatment of articular infection, thereafter, searching for a biomarker with high sensitivity and specificity is necessary.

OBJECTIVE: To systematically evaluate the value of procalcitonin for diagnosing joint infection in adult.
METHODS: A computer-based online research was performed for the literature in PubMed, EMbase, the Cochrane Library and CNKI databases from 1990 to June 2017. Literature screening and data extraction were conducted by two reviewers independently according to the inclusion and exclusion criteria. The risk of bias of included studies was assessed by using the Quality Assessment of Diagnostic Accuracy Studies-2. Meta-analysis was then performed using Stata 14.0 software. The pooled weighted sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio were calculated; the summary receiver operating characteristic curve was drawn and the area under the curve was calculated.
RESULTS AND CONCLUSION: (1) A total of 10 studies were included, involving 893 patients. (2) The pooled weighted sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio of procalcitonin diagnosing joint infection were 0.82 (95%CI=0.72-0.89), 0.89 (95%CI=0.82-0.93), 7.20 (95%CI=4.6-11.3), 0.20 (95%CI=0.13-0.32), 35 (95%CI=18-71) and 0.92 (95%CI=0.90-0.94), respectively. (3) To conclude, procalcitonin exhibits more diagnostic efficiency for assessing articular infection in adults.
