BACKGROUND Randomized Controlled Trials almost invariably utilize the hazard ratio calculated with a Cox proportional hazard model as a treatment efficacy measure. Despite the widespread adoption of HRs, these provide a limited understanding of the treatment effect and may even provide a biased estimate when the assumption of proportional hazards in the Cox model is not verified by the trial da...

This paper studies the deterioration of bridge substructures utilizing Long-Term Bridge Performance (LTBP) Program InfoBridgeTM and develops a survival model using Cox proportional hazards regression. The analysis is based on National Inventory (NBI) dataset. study calculates rate reinforced prestressed concrete piles bridges under marine conditions over 29-year span (from 1992 to 2020). state ...

Abstract Survival (overall, event free, etc.) is the most-used outcome in clinical oncology studies. This study analyzed methodological reporting of survival analysis pediatric leukemia studies, focusing on Cox proportional hazards (PH). We performed a systematic review studies published between 2012 and 2021 five highest-ranking hematology journals. The included had to focus utilize analyses. ...
