Survival Curves01:18

Survival Curves

732
Survival curves are graphical representations that depict the survival experience of a population over time, offering an intuitive way to track the proportion of individuals who remain event-free at each time point. These curves are widely used in fields such as medicine, public health, and reliability engineering to visualize and compare survival probabilities across different groups or conditions.
The Kaplan-Meier estimator is the most common method for constructing survival curves. This...

Survival Tree01:19

Survival Tree

436
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Introduction To Survival Analysis

831
Survival analysis is a statistical method used to study time-to-event data, where the "event" might represent outcomes like death, disease relapse, system failure, or recovery. A unique feature of survival data is censoring, which occurs when the event of interest has not been observed for some individuals during the study period. This requires specialized techniques to handle incomplete data effectively.
The primary goal of survival analysis is to estimate survival time—the time...

Comparing the Survival Analysis of Two or More Groups

617
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Truncation in Survival Analysis01:09

Truncation in Survival Analysis

635
Truncation in survival analysis refers to the exclusion of individuals or events from the dataset based on specific criteria related to the time of the event. This exclusion can happen in two primary forms: left truncation and right truncation.
Left truncation occurs when individuals who experienced the event of interest before a certain time are not included in the study. This is often due to a "delayed entry" into the study where only those who survive until a certain entry point are...

Assumptions of Survival Analysis01:15

Assumptions of Survival Analysis

433
Survival models analyze the time until one or more events occur, such as death in biological organisms or failure in mechanical systems. These models are widely used across fields like medicine, biology, engineering, and public health to study time-to-event phenomena. To ensure accurate results, survival analysis relies on key assumptions and careful study design.

Summary

UK child mortality rates lag behind comparable wealthy nations, with significant divergence in under-10s mortality. Without intervention, UK infant and young child mortality may exceed EU15+ medians by 2030.

Area of Science:

  • Public Health
  • Pediatric Mortality Trends
  • International Comparative Analysis

Background:

  • The Countdown for UK Child Survival initiative monitors child mortality trends in the UK.
  • It provides recommendations for enhancing child survival rates.

Purpose of the Study:

  • To analyze UK child mortality trends from 1970-2014.
  • To compare UK mortality rates with a group of wealthy nations (EU15+).
  • To project future disparities and propose goals aligned with UN Sustainable Development Goals.

Main Methods:

  • Utilized WHO World Mortality Database for mortality data (ages 0-19).
  • Employed Poisson regression models to assess significant differences.
  • Extrapolated trends to forecast 2030 disparities between the UK and EU15+.

Main Results:

  • UK infant mortality is in the worst decile, and 1-4 year mortality in the worst quartile compared to EU15+.
  • Annual mortality reductions in the UK have been slower than EU15+ since 1990.
  • Projected 2030 UK infant and 1-4 year mortality could be 180% and 145% of EU15+ median, respectively.
  • UK non-communicable disease (NCD) mortality for ages 1-4 and 15-19 remains poor.

Conclusions:

  • UK child mortality (under 10) is diverging from EU15+ medians.
  • Persistent high NCD mortality in UK children is a concern.
  • Proposed goals and an annual monitoring mechanism aim to improve UK childhood survival by 2030.
