Propensity score–weighted analysis of neoadjuvant therapy versus upfront surgical resection in patients with biliary tract cancersBiliary Tract CancerNeoadjuvant TherapyBile tract cancer (BTC) is a heterogeneous and aggressive malignancy with a poor prognosis. Surgical resection is the main potentially ...
This patient-level propensity score-weighted analysis, which was well balanced for key baseline covariates, demonstrated that tebentafusp resulted in significantly superior OS (HR 0.52; 95% CI 0.35-0.78) compared with nivolumab plus ipilimumab in patients with previously untreated mUM. Based on the...
倾向性得分(Propensity Score,PS)就是在给定一组协变量的条件下,研究对象被分配到处理组的条件概率,这个概率一般通过logit或者probit模型来获取。倾向性得分本身并不能控制混杂,而是需要通过进一步的匹配、分层、回归校正、加权等方式来达到分析的目的。 既往倾向性得分分析一些笔记: 倾向性得分匹配(PSM); 倾向性得分匹...

and control cases that look like they should have got the treatment are interesting and get more weight. Analysis can then proceed via weighted average values, or a regression with explanatory variables (which may or may not be the same variables as those used in the model of propensity for ...
Briefly, propensity score weights were derived from patient demographic and clinical characteristics. High HRU was measured as a binary indicator defined as a length of stay greater than 7 days and/or discharge to a non-home setting. Cost was measured as total charges, which was standardized to...
