歡迎來到醫科研,這里是白介素2的讀書筆記,跟我一起聊臨床與科研的故事, 生物醫學數據挖掘文獻分享,R語言,TCGA數據、GEO數據庫, SEER數據挖掘, 臨床預測模型研究。 簡介:近年來關于預測模型的文章很多,但很多相關研究都存在各種各樣的不規范,也就是開發的模型成千上萬,正能用的少之又少。關于那些 prognostic gene model就更不用說了,今天灌明天灌肯定是不行的。 前文我們已經對TRIPOD聲明的內容即背景進行了介紹預測模型第3篇|你的預測模型文章報告是規范的嗎?,本文對TRIPOD checklist-開發預測模型進行詳細解讀。 要發表高質量的臨床預測模型研究,應該參考真正規范的報告模型,我們根據這一的一個checklist來幫助我們查缺補漏。絕知此事要躬行,這里白介素2整理閱讀了來自 TRIPOD checklist文件,全文如下,如有不當之處,請諸位斧正。 標題-Title
摘要-Abstrat
文章的摘要部分應該概括 目的,研究設計,納入人群,樣本量,預測因素,預測結局,統計分析,結果,文章結論 。一個好的摘要通常是簡明扼要的,但又不缺失這些信息,在臨床預測模型文章準備過程中應該按照這些核心元素去撰寫。 前言-Introduction3a. Explain the medical context (including whether diagnostic or prognostic) and rationale for developing or validating the multivariable prediction model, including references to existing models.
3b. Specify the objectives, including whether the study describes the development or validation of the model or both.
方法學數據來源-Source of data4a. Describe the study design or source of data (e.g., randomized trial, cohort, or registry data), separately for the development and validation data sets, if applicable
4b. Specify the key study dates, including start of accrual; end of accrual; and, if applicable, end of follow-up.
參與對象- Participants5a. Specify key elements of the study setting (e.g., primary care, secondary care, general population) including number and location of centres. 5b. Describe eligibility criteria for participants. 5c. Give details of treatments received, if relevant.
結局-Outcome6a. Clearly define the outcome that is predicted by the prediction model, including how and when assessed. 6b. Report any actions to blind assessment of the outcome to be predicted.
預測因素-Predictors7a. Clearly define all predictors used in developing or validating the multivariable prediction model, including how and when they were measured. 7b. Report any actions to blind assessment of predictors for the outcome and other predictors.
樣本量-Sample size
缺失數據-Missing data
統計方法-Statistical analysis methods10a. Describe how predictors were handled in the analyses. 10b. Specify type of model, all model-building procedures (including any predictor selection), and method for internal validation. 10d. Specify all measures used to assess model performance and, if relevant, to compare multiple models.
風險分組-Risk group
結果參與對象13a. Describe the flow of participants through the study, including the number of participants with and without the outcome and, if applicable, a summary of the follow-up time. A diagram may be helpful. 13b. Describe the characteristics of the participants (basic demographics, clinical features, available predictors), including the number of participants with missing data for predictors and outcome.
模型開發-Model development14a. Specify the number of participants and outcome events in each analysis 14a. If done, report the unadjusted association between each candidate predictor and outcome.
模型的具體說明-Model specification15a. Present the full prediction model to allow predictions for individuals (i.e., all regression coefficients, and model intercept or baseline survival at a given time point). 15b. Explain how to the use the prediction model.
模型的性能-Model performance
討論局限性-Limitations
解釋-Interpretation19b. Give an overall interpretation of the results, considering objectives, limitations, and results from similar studies, and other relevant evidence.
啟示-Implications
其它信息-Other information補充信息-Supplementary information
資助信息-Funding
