Modelling Survival Data in Medical Research
TLDR
This third edition of Modelling Survival Data in Medical Research contains new chapters on frailty models and their applications, competing risks, non-proportional hazards, and dependent censoring.Abstract:
Modelling Survival Data in Medical Research 3rd Edition Dec 04, 2014 · Modelling Survival Data in Medical Research describes the modelling approach to the analysis of survival data using a wide range of examples from biomedical research. Well known for its nontechnical style, this third edition contains new chapters on frailty models and their applications, competing risks, non-proportional hazards, and dependent censoring. It also describes techniques forread more

Visual Tracking: An Experimental Survey
Arnold W. M. Smeulders,Dung M. Chu,Rita Cucchiara,Simone Calderara,Afshin Dehghan,Mubarak Shah +5 more
TL;DR: It is demonstrated that trackers can be evaluated objectively by survival curves, Kaplan Meier statistics, and Grubs testing, and it is found that in the evaluation practice the F-score is as effective as the object tracking accuracy (OTA) score.

High incidence of anal high-grade squamous intra-epithelial lesions among HIV-positive and HIV-negative homosexual and bisexual men.
TL;DR: HIV infection, lowerCD4 levels and human papillomavirus infection were associated with high rates of incident HSIL among homosexual men, however, high rates were found at all CD4 levels among HIV-positive men and among HIV -negative men.

TL;DR: Risk of multiple sclerosis in children can be stratified by presence of HLA-DRB1*15 alleles, remote Epstein-Barr virus infection, and low serum 25-hydroxyvitamin D concentrations, suggesting established disease.

Long-term risk of carotid restenosis in patients randomly assigned to endovascular treatment or endarterectomy in the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS): long-term follow-up of a randomised trial
Leo H. Bonati,Jörg Ederle,Dominick J. H. McCabe,Joanna Dobson,Roland L Featherstone,Peter Gaines,Jonathan Beard,Graham Venables,Hugh S. Markus,Andrew Clifton,Peter Sandercock,Martin M. Brown +11 more
TL;DR: Restenosis is about three times more common after endovascular treatment than after endarterectomy and is associated with recurrent ipsilateral cerebrovascular symptoms; however, the risk of recurrent embedding stroke is low and further data are required to ascertain whether long-term ultrasound follow-up is necessary after carotid revascularisation.
Journal ArticleDOI
Improved curve fits to summary survival data: application to economic evaluation of health technologies.
TL;DR: The proposed method achieves similar bias and mean square error when estimating the mean survival time to that achieved by analysis of the complete underlying individual patient data and naturally yields estimates of the uncertainty in curve fits, which are not available using the traditional methods.

Survival Analysis Part I: Basic concepts and first analyses
TL;DR: Multivariate survival analysis, a form of multiple regression, provides a way of doing this adjustment for patient-related factors that could potentially affect the survival time of a patient, and is the subject of the next paper in this series.
