Inverse Probability Weighted Cox Regression for Doubly Truncated Data [PDF]

Biometrics, 2017
SummaryDoubly truncated data arise when event times are observed only if they fall within subject-specific, possibly random, intervals. While non-parametric methods for survivor function estimation using doubly truncated data have been intensively studied, only a few methods for fitting regression models have been suggested, and only for a limited ...

Antiepileptic Drug Use and the Risk of Stroke Among Community‐Dwelling People With Alzheimer Disease: A Matched Cohort Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background People with Alzheimer disease (AD) are more predisposed to seizures than older people in general, and use of antiepileptic drugs (AEDs) is more frequent.

Impact of acute cholecystitis comorbidity on prognosis after surgery for gallbladder cancer: a propensity score analysis

World Journal of Surgical Oncology, 2023
Background Cholecystitis can represent a comorbidity during gallbladder cancer surgery; nonetheless, the prognostic impact of acute cholecystitis comorbidity remains unclear.

Responsiveness-informed multiple imputation and inverse probability-weighting in cohort studies with missing data that are non-monotone or not missing at random [PDF]

, 2016
Population-based cohort studies are invaluable to health research because of the breadth of data collection over time, and the representativeness of their samples.

Splenic hilar lymph node dissection enhances survival in Bormann type 4 gastric cancer

Scientific Reports, 2023
Splenic hilar (no.10) lymph node dissection during total gastrectomy is no longer recommended for advanced proximal gastric cancer. However, the treatment efficacy of no.10 lymph node dissection in Borrmann type 4 tumors remains unclear.

Teclistamab versus real-world physician’s choice of therapy in triple-class exposed relapsed/refractory multiple myeloma

Journal of Comparative Effectiveness Research, 2023
Aim: We compared the effectiveness of teclistamab versus real-world physician’s choice of therapy (RWPC) in triple-class exposed relapsed/refractory multiple myeloma. Materials & methods: MajesTEC- 1 eligibility criteria were applied to the RWPC cohort.

Unicompartmental compared with total knee replacement for patients with multimorbidities: a cohort study using propensity score stratification and inverse probability weighting

Health Technology Assessment, 2021
Background: Although routine NHS data potentially include all patients, confounding limits their use for causal inference. Methods to minimise confounding in observational studies of implantable devices are required to enable the evaluation of patients ...

Adjustment for treatment changes in epilepsy trials: A comparison of causal methods for time-to-event outcomes [PDF]

, 2017
BACKGROUND: When trials are subject to departures from randomised treatment, simple statistical methods that aim to estimate treatment efficacy, such as per protocol or as treated analyses, typically introduce selection bias. More appropriate methods to

Variance reduction in randomised trials by inverse probability weighting using the propensity score. [PDF]

, 2013
In individually randomised controlled trials, adjustment for baseline characteristics is often undertaken to increase precision of the treatment effect estimate. This is usually performed using covariate adjustment in outcome regression models.
