Kaplan-Meier Approach01:24

Kaplan-Meier Approach

648
The Kaplan-Meier estimator is a non-parametric method used to estimate the survival function from time-to-event data. In medical research, it is frequently employed to measure the proportion of patients surviving for a certain period after treatment. This estimator is fundamental in analyzing time-to-event data, making it indispensable in clinical trials, epidemiological studies, and reliability engineering. By estimating survival probabilities, researchers can evaluate treatment effectiveness,...

Diabetes: Symptoms, Diagnosis, and Complications

2.5K
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Area of Science:

  • Gerontology
  • Diabetology
  • Biostatistics

Background:

  • Established mortality prediction models exist for the general diabetic population.
  • A specific, validated model for elderly individuals with diabetes is currently lacking.
  • Accurate risk stratification is crucial for managing diabetes in older adults.

Purpose of the Study:

  • To develop and validate a mortality prediction model tailored for elderly patients with diabetes (≥65 years).
  • To identify significant predictors of five-year mortality in this demographic.
  • To create an accessible tool for assessing mortality risk in older diabetic individuals.

Main Methods:

  • Utilized data from Taiwan's nationwide adult health screening program (2007-2010) for model construction.
  • Employed 10-fold cross-validation for internal validation.
  • Performed external validation using the MJ health screening database (2004-2007).
  • Applied multivariable Cox proportional hazards models to predict five-year mortality.

Main Results:

  • The final model included predictors such as age, gender, BMI, fasting glucose, blood pressure, and various biochemical markers (e.g., cholesterol, hemoglobin, albumin).
  • The model demonstrated good predictive performance with Harrell's C values of 0.737 (development), 0.746 (internal validation), and 0.685 (external validation).
  • A total of 220,832 older diabetic subjects were analyzed, with a 10.5% five-year mortality rate.

Conclusions:

  • An easy-to-use, point-based mortality prediction model for elderly individuals with diabetes was successfully developed.
  • The model provides accurate five-year mortality risk assessment for older adults with diabetes.
  • This tool can support clinical decision-making and proactive healthcare management for geriatric diabetic patients.
