目的
2
基于五味苦参肠溶胶囊治疗溃疡性结肠炎的患者数据,探讨中医药疗效预测模型构建的可行性及其方法要点。
方法
2
选择五味苦参肠溶胶囊Ⅲ期临床试验的试验组(五味苦参肠溶胶囊)作为研究对象,经过8周试验后,数据资料完整的患者共274例。统计分析软件使用R语言4.1.0,纳入全部待筛选变量构建多因素Logistic回归模型,筛选
P
<
0.05的变量纳入最终模型;绘制列线图;采用Bootstrap法重复抽样1 000次对模型进行内部验证,计算C指数并绘制校准图,评价模型的区分度及校准度;并进行Hosmer-Lemeshow拟合优度检验和外部验证,对模型进行总体评价。
结果
2
筛选出溃疡性结肠炎完全缓解的促进因素为:患者(15~65岁)接受治疗时年龄小(
OR
=0.96
95%
CI:
0.94~0.99
P
=0.002 )、非慢性持续型(与初发型比,
OR
=0.36
95%
CI
:0.18~0.74
P
=0.005)、镜下无出血(
OR
=0.42,95%
CI
:0.22~0.82,
P
=0.011)、红细胞沉降率降低(
OR
=0.97,95%
CI
:0.95~0.99,
P
=0.006)。使用上述变量构建最终模型,并绘制列线图,校正后的C指数为0.735(95%
CI
:0.672~0.797),模型区分度尚可;绘制校准图可见校准曲线与标准线大致贴合,模型校准度尚可。对模型进行Hosmer-Lemeshow拟合优度检验(
χ
2
=7.07,
P
=0.53),模型拟合良好。对模型进行外部检证,C指数及置信区间为0.54(95%
CI
:0.44~0.65)。
结论
2
利用随机对照试验的数据进行预测模型构建具有一定可行性;根据本研究的数据所建立的预测模型,经过大样本验证后,有可能为临床监测和针对性治疗提供有效的测评工具。
Objective
2
Based on the data of patients with ulcerative colitis treated with Five-Flavor Sophora Flavescens Radix Enteric-coated Capsules
we discuss the feasibility and methodology of constructing a prediction model of the efficacy of traditional Chinese medicine.
Methods
2
Based on phase Ⅲ clinical trial data of Five-Flavor Sophora Flavescens Radix Enteric-coated Capsules
a total of 274 patients with active ulcerative colitis with complete population data after 8 weeks of treatment in the experimental group (Five-Flavor Sophora Flavescens Radix Enteric-coated Capsules) were selected. R 4.1.0 was used for statistical analysis. First
all the variables to be screened were included to construct a multivariate Logistic regression model. Then
variables with
P
<
0.05 were screened for inclusion in the final model. The nomogram was plotted. The bootstrap method was used to resample 1 000 times for internal validation of the model
the C index was calculated
and the calibration chart was plotted to evaluate the discrimination and calibration of the model. The model was evaluated by the Hosmer-Lemeshow goodness of fit test and external validation. The overall evaluation of the model was performed by the above methods.
Results
2
The prognostic factors for complete remission of ulcerative colitis were younger age (15-65 years old) (
OR
=0.96
95%
CI
: 0.94-0.99
P
=0.002)
non-chronic persistent (compared with primary type) (
OR
=0.36
95%
CI
: 0.18-0.74
P
=0.005)
no microscopic bleeding (
OR
=0.42
95%
CI
: 0.22-0.82
P
=0.011)
and decreased erythrocyte sedimentation rate (
OR
=0.97
95%
CI
: 0.95-0.99
P
=0.006). We used the above variables to construct the final model and drew a nomogram. The corrected C index was 0.735 (95%
CI
: 0.672-0.797)
indicating that the model’s discrimination was acceptable. The calibration diagram shows that the calibration curve and the standard line roughly fit
indicating the calibration model is acceptable. The Hosmer-Lemeshow goodness of fit test (χ
2
=7.07
P
=0.53) showed that the model was well fitted. We conducted an external test of the prediction model. The C index and confidence interval were 0.54(95%
CI
: 0.44-0.65).
Conclusion
2
It is feasible to construct a prediction model by using data from randomized controlled trials. A prediction model based on the study data may provide an effective evaluation tool for clinical monitoring and targeted therapy after large sample validation.
