目的建立基于增强CT的影像组学模型,评估其鉴别肾透明细胞癌(ccRCC)与非透明细胞癌(non-ccRCC)的应用价值。方法将147例ccRCC及32例non-ccRCC患者随机分为训练集125例和测试集54例。将所有患者的增强CT资料导入ITK-SNAP软件,手动勾画ROI... 目的建立基于增强CT的影像组学模型,评估其鉴别肾透明细胞癌(ccRCC)与非透明细胞癌(non-ccRCC)的应用价值。方法将147例ccRCC及32例non-ccRCC患者随机分为训练集125例和测试集54例。将所有患者的增强CT资料导入ITK-SNAP软件,手动勾画ROI,获得16个特征,分别建立基于特征的随机森林(RF)模型和逻辑回归(LR)模型,采用ROC曲线观察模型对ccRCC的诊断效能。结果训练集RF模型诊断ccRCC的AUC为0.96(P<0.05),特异度为1.00,敏感度0.83;LR模型诊断ccRCC的AUC为0.96(P<0.05),特异度为1.00,敏感度为0.83。测试集RF模型诊断ccRCC的AUC为0.96(P<0.05),特异度为1.00,敏感度为0.89;LR模型诊断ccRCC的AUC为0.88(P<0.05),特异度为0.90,敏感度为0.77。结论基于增强CT影像组学模型可用于鉴别ccRCC与non-ccRCC;RF模型诊断价值较LR模型更高。 展开更多

Objective:To assess the reliability of the methodological quality and outcome measures of systematic reviews(SR)/meta-analysis of premature ovarian insufficiency(POI) treated with acupuncture.Methods:SR/meta-analysis of POI treated with acupuncture were searched on POI from the databases including PubMed,Web of Science,EMBase,the Cochran Library,Chinese biomedical literature database(SinoMed),China journal full-text database(CNKI),Wanfang data knowledge service platform(Wanfang)and VIP information Chinese periodical service platform(VIP),from inception to 1 st May 2021.Using A Measurement Tool to Assess Systematic Reviews 2(AMSTAR 2) scale and Grades of Recommendations Assessment,Development and Evaluation(GRADE) system,the methodological quality and outcome measures of the included studies were appraised.Results:Ten articles of SR/meta-analysis were included,published from 2015 to 2020.Using AMSTAR 2,5 articles of SR/meta-analysis were rated as critical low quality in methods,3 articles as low quality,and2 articles as moderate quality.The results of GRADE showed that among the 50 outcomes the quality of evidence of 22 outcomes was very low,that of 25 outcomes was low and that of 3 outcomes was moderate.Conclusion:The methodological quality and the reliability of outcome measures were not high in existing SR/meta-analysis on POI treated with acupuncture,which may affect the translation of the SR/metaanalysis findings into clinical practice.It is necessary to further strengthen the methodological quality and reporting standard of SR/meta-analysis,as well as the robustness of design and implementation of randomized controlled trials(RCTs),in order to generate high quality evidences for clinical decision-making and practice. 展开更多
