Competing risk bias was common in Kaplan-Meier risk estimates published in prominent medical journals.

Journal of clinical epidemiology

van Walraven C, McAlister FA.
PMID: 26232083
J Clin Epidemiol. 2016 Jan;69:170-3.e8. doi: 10.1016/j.jclinepi.2015.07.006. Epub 2015 Jul 29.

OBJECTIVE: Risk estimates from Kaplan-Meier curves are well known to medical researchers, reviewers, and editors. In this study, we determined the proportion of Kaplan-Meier analyses published in prominent medical journals that are potentially biased because of competing events ("competing...

Impact of mental health problems on case fatality in male cancer patients.

British journal of cancer

Batty GD, Whitley E, Gale CR, Osborn D, Tynelius P, Rasmussen F.
PMID: 22516950
Br J Cancer. 2012 May 22;106(11):1842-5. doi: 10.1038/bjc.2012.150. Epub 2012 Apr 19.

BACKGROUND: Although mortality rates are elevated in psychiatric patients relative to their healthy counterparts, little is known about the impact of mental health on survival in people with cancer.METHODS AND RESULTS: Among 16 498 Swedish men with cancer, survival...

Bias-adjusted Kaplan-Meier survival curves for marginal treatment effect in observational studies.

Journal of biopharmaceutical statistics

Wang X, Bai F, Pang H, George SL.
PMID: 31286838
J Biopharm Stat. 2019;29(4):592-605. doi: 10.1080/10543406.2019.1633659. Epub 2019 Jul 09.

For time-to-event outcomes, the Kaplan-Meier estimator is commonly used to estimate survival functions of treatment groups and to compute marginal treatment effects, such as the difference in survival rates between treatments at a landmark time. The derived estimates of...

Prospective Study of Cancer Genetic Variants: Variation in Rate of Reclassification by Ancestry.

Journal of the National Cancer Institute

Slavin TP, Van Tongeren LR, Behrendt CE, Solomon I, Rybak C, Nehoray B, Kuzmich L, Niell-Swiller M, Blazer KR, Tao S, Yang K, Culver JO, Sand S, Castillo D, Herzog J, Gray SW, Weitzel JN.
PMID: 29618041
J Natl Cancer Inst. 2018 Oct 01;110(10):1059-1066. doi: 10.1093/jnci/djy027.

BACKGROUND: In germline genetic testing, variants from understudied ancestries have been disproportionately classified as being of uncertain significance. We hypothesized that the rate of variant reclassification likewise differs by ancestry.METHODS: Nonbenign variants in actionable genes were collected from consenting...

Validation of a Score Developed to Estimate the 6-month Survival of Patients Treated with Palliative Local Radiotherapy for Advanced Lung Cancer.

Laryngoscope. 2020 Feb;130(2):514-520. doi: 10.1002/lary.27888. Epub 2019 Mar 05.

OBJECTIVES/HYPOTHESIS: Timing and indication for surgical intervention is a major challenge in managing pediatric oropharyngeal dysphagia. No study has evaluated a natural course of swallowing dysfunction in otherwise healthy infants. Our objective was to review the outcomes and time...

geneSurv: An interactive web-based tool for survival analysis in genomics research.

Computers in biology and medicine

Korkmaz S, Goksuluk D, Zararsiz G, Karahan S.
PMID: 28889076
