摘要
目的系统评价糖化血红蛋白(HbA1c)≥6.5%在中国成人糖尿病诊断中的价值。方法计算机检索国内外重要数据库,搜索有关HbA1c≥6.5%在中国成人中糖尿病诊断价值的文献。采用诊断性试验准确性质量评价工具(QUADAS)评价纳入文献质量,应用Meta-Disc1.4软件对纳入研究进行综合定量评价,并绘制综合ROC(SROC)曲线。结果共纳入11篇文献。对于HbA1c≥6.5%在中国成人中的诊断价值为:合并敏感度为0.62(95%CI:0.60~0.64),合并特异度为0.96(95%CI:0.95~0.96),诊断性比值比(DOR)为40.25(95%CI:20.79—77.95),AUCSROC为0.7702(sx=0.0636),Q=0.7103(sx=0.0537)。结论HbA1c≥6.5%在中国成人糖尿病中的诊断特异度非常高,但敏感度相对较低,存在一定的漏诊率,需结合血糖检测以降低漏诊率。
Objective To assess the diagnostic value of glycosylated hemoglobin Alc (HbAlc) ≥ 6.5% for diabetes in Chinese adults with oral glucose tolerance test(OGTT) as the reference standard. Methods Major databases were searched to get all diagnostic tests with HbAlc I〉6. 5% for diabetes in Chinese adults. QUADAS items were used to evaluate the quality of the eligible studies. Meta-disc software was used to perform comprehensive quantitative assessment for all included studies and summary ROC (SROC) curve were drawn. Results A total of 11 studies were included. The outcomes of the diagnostic value with HbAlc I〉 6. 5% were as the following: pooled sensitivity 0. 62 ( 95% CI: 0. 60-0. 64), pooled specificity 0. 96 (95% CI: 0. 95-0. 96 ), diagnostic odds ratio ( DOR ) 40. 25 ( 95% CI: 20. 79-77.95 ) and AUCSROC 0. 7702 (sx =0. 0636). Conclusions The diagnostic specificity is pretty high for the diagnostic test with HbA1c≥6. 5%, while sensitivity is low. Combination of HbA1c and glucose tests is needed to reduce the missed diagnosis rate.
