摘 要:目的构建临床诊断模型区分肺结核与非结核性肺病。方法收集258例呼吸系统疾病的患者信息,通过R软件采用随机数种子的方式分为训练集152例,测试集106例,比例为6∶4,根据患者诊断是否为肺结核将训练集分为结核组95例和非结核组57例,测试集分为结核组65例和非结核组41例。根据多因素Logistic回归分析确定肺结核影响因素并构建诊断模型,采用受试者工作特征(ROC)曲线、校准曲线及临床决策曲线(DCA)评估诊断模型的预测价值和临床实用性。结果CD161+%(OR=0.768;95%CI 0.697~0.845;P<0.001)、AST(OR=0.961;95%CI 0.930~0.993;P=0.019)、吸烟史(OR=3.181;95%CI 1.149~8.804;P=0.026)是肺结核发生的独立影响因素。在训练集和测试集中,ROC曲线下面积(AUC)达到了0.870(95%CI 0.816~0.924)和0.887(95%CI 0.827~0.948),Hosmer-Lemeshow拟合优度检验结果显示,拟合度较好(训练集χ^(2)=6.213,P=0.623;测试集χ^(2)=6.197,P=0.625)。DCA表明该模型对肺结核发生概率诊断具有较好的参考意义。结论利用CD161+%、AST、吸烟史构建诊断模型具有一定的诊断性能,便于临床快速区别肺结核与非结核性肺病。Objective To construct and validate a clinical diagnostic model to differentiate between pulmonary tuberculosis and non-tuberculous lung diseases.Methods Information was collected from 258 patients with respiratory system diseases,and they were divided into a training set of 152 cases and a test set of 106 cases with a ratio of 6∶4 using the random number seed method in R software.The training set was further divided into a tuberculosis group of 95 cases and a non-tuberculosis group of 57 cases,and the test set into a tuberculosis group of 65 cases and a non-tuberculosis group of 41 cases based on the diagnosis of pulmonary tuberculosis.A diagnostic model was constructed using multivariate logistic regression analysis to determine the influencing factors of pulmonary tuberculosis.The diagnostic value and clinical utility of the model were assessed using the receiver operating characteristic(ROC)curve,calibration curve,and decision curve analysis(DCA).Results CD161+%(OR=0.768;95%CI 0.697-0.845;P<0.001),AST(OR=0.961;95%CI 0.930-0.993;P=0.019),and smoking history(OR=3.181;95%CI 1.149-8.804;P=0.026)were identified as independent risk factors for the occurrence of pulmonary tuberculosis.In both the training and test sets,the area under the ROC curve(AUC)reached 0.870(95%CI 0.816-0.924)and 0.887(95%CI 0.827-0.948),respectively.The Hosmer-Lemeshow goodness-of-fit test showed a good fit(training setχ^(2)=6.213,P=0.623;test setχ^(2)=6.197,P=0.625).DCA indicated that the model had good reference significance for the diagnosis of the probability of pulmonary tuberculosis occurrence.Conclusion The diagnostic model constructed using the percentage of CD161+%,AST levels,and smoking history has certain diagnostic performance,facilitating rapid clinical differentiation between pulmonary tuberculosis and non-tuberculous lung diseases.
