Survival Analysis, Kaplan-Meier Curves, and Cox Regression: Basic Concepts [PDF]

open access: yesIndian Journal of Psychological Medicine, 2023
Survival analysis is used to analyze data from patients who are followed for different periods of time and in whom the outcome of interest, a dichotomous event, may or may not have occurred at the time the study is halted; data from all patients are used

Reconstructing patient level survival data from published Kaplan-Meier curves [PDF]

open access: yesContemporary Clinical Trials Communications
Introduction: Individual-level patient data (IPD) are helpful for designing clinical trials, conducting meta-analyses, or methodology research. However, such patient level data are not readily available.

IPDfromKM: reconstruct individual patient data from published Kaplan-Meier survival curves [PDF]

open access: yesBMC Medical Research Methodology, 2021
Background When applying secondary analysis on published survival data, it is critical to obtain each patient’s raw data, because the individual patient data (IPD) approach has been considered as the gold standard of data analysis.

KMSubtraction: reconstruction of unreported subgroup survival data utilizing published Kaplan-Meier survival curves [PDF]

open access: yesBMC Medical Research Methodology, 2022
Background Data from certain subgroups of clinical interest may not be presented in primary manuscripts or conference abstract presentations. In an effort to enable secondary data analyses, we propose a workflow to retrieve unreported subgroup survival ...

KAPLAN-MEIER AND NELSON-AALEN ESTIMATORS FOR CREDIT SCORING

open access: yesMedia Statistika, 2023
Financial institutions use credit scoring analysis to predict the probability that a customer will default. In this paper, we determine the probability of default using nonparametric survival analysis that are Kaplan-Meier and Nelson-Aalen.

Using the Kaplan–Meier Estimator to Assess the Reliability of Agricultural Machinery

open access: yesAgronomy, 2022
Kaplan–Meier analyses can be used in many disciplines, e.g., agricultural engineering. Agricultural machinery and vehicles can be regarded as objects that ‘die’ because, like living creatures, they failed, although after repair they can be used until ...

Estimating the effect of healthcare-associated infections on excess length of hospital stay using inverse probability-weighted survival curves [PDF]

open access: yes, 2020
Background: Studies estimating excess length of stay (LOS) attributable to nosocomial infections have failed to address time-varying confounding, likely leading to overestimation of their impact.
