The aim of this study is to externally validate the MSKCC nomogram in the UK population, and determine its usefulness. Method The colon cancer database from a district general hospital in England was used to extract all patients who had a curative colon cancer resection. Inclusion criteria were...
具体目标包括:①掌握Logistic回归模型的全面验证方法;②学会创建和优化Nomogram图;③理解并应用决策曲线分析。 其他说明:文章不仅提供理论指导,还附带详细的代码示例,帮助读者更好地理解和实践。同时,强调了模型验证过程中常见的陷阱和注意事项,如数据预处理、非线性关系处理等。
The multidimensional nomogram calculating the upper limit of normal PTH (maxPTH) model identifies a personalized upper limit of normal parathyroid hormone (PTH) and successfully predicts classical primary hyperparathyroidism (PHP). We aimed to assess whether maxPTH can distinguish normocalcemic PHP (NC...
The DCA curve suggested that the nomogram model was better than TIMI score model in terms of net clinical benefit.Conclusion: Serum PTH levels in patients with STEMI are associated with in-hospital MACE after primary PCI, and the nomogram risk prediction model based on PTH demon...
Scott et al previously modelled the cost-effectiveness of additional IgA measurement on the predictive value of CD screening and found it to be ineffective and unnecessary in improving test predictive outcomes using Fagan9s nomogram at 1 in 50 prevalence. The relationship of IgA deficiency with ...
The maxPTH nomogram functions as expected to classify patients with PHP and may aid in the diagnosis of NCPHP regardless of vitamin D status and repletion, reassuring primary providers and surgeons alike to embark on appropriate and timely PHP management....
