There is still controversy over the value of renal angina index (RAI) in predicting acute renal failure (AKI) in children. Therefore, the present study aims to provide evidence by conducting a systematic review and meta-analysis on the value of RAI in this regard.
An extensive search of Medline, Embase, Scopus and Web of Science databases was conducted by the end of January 2020 using words related to RAI and AKI. Two independent reviewers screened and summarized the related studies. Data were analysed using STATA 14.0 statistical program and discriminatory precision of RAI was assessed.
Data from 11 studies were included. These studies included data from 3701 children (60.41% boys). There were 752 children with AKI and 2949 non-AKI children. Pooled analysis showed that the area under the ROC curve of RAI in prediction of AKI was 0.88 [95% confidence interval (CI): 0.85 to 0.91]. Sensitivity and specificity of this tool in predicting AKI were 0.85% (95% CI: 0.74% to 0.92%) and 0.79% (95% CI: 0.69% to 0.89%), respectively. The diagnostic odds ratio of RAI was 20.40 (95% CI: 9.62 to 43.25).
The findings of the present meta-analysis showed that RAI is a reliable tool in predicting AKI in children.
肾绞痛指数（RAI）在预测儿童急性肾衰竭（AKI）方面的价值仍存在争议。因此，本研究旨在通过对RAI在这方面的价值进行系统评价和荟萃分析来提供证据。
截至2020年1月，使用与RAI和AKI相关的词汇对Medline、Embase、Scopus和Web of Science数据库进行了广泛检索。两名独立的评审员筛选并总结了相关研究。使用STATA 14.0统计程序分析数据，并评估RAI的鉴别精度。
纳入了11项研究的数据。这些研究包括来自3701名儿童的数据（60.41%为男孩）。有752名AKI儿童和2949名非AKI儿童。汇总分析显示，RAI预测AKI的ROC曲线下面积为0.88[95%置信区间（CI）：0.85至0.91]。该工具预测AKI的敏感性和特异性分别为0.85%（95%CI：0.74%至0.92%）和0.79%（95%CI：0.69%至0.89%）。RAI的诊断比值比为20.40（95%CI：9.62至43.25）。
本荟萃分析的结果表明，RAI是预测儿童AKI的可靠工具。
