Stratification by a multivariate confounder score

American Journal of Epidemiology

|December 1, 1976

Summary

This summary is machine-generated.

Researchers can simplify controlling confounding factors in etiologic research by using a multivariate score. This method, involving stratification by the score, offers a more efficient approach to analyzing confounding patterns.

Area of Science:

Epidemiology
Biostatistics

Background:

Controlling confounding is crucial in etiologic research to accurately assess causal relationships.
Traditional methods like multiple cross-classification can be complex and inefficient.

Purpose of the Study:

To propose a more efficient method for controlling confounding in etiologic research.
To introduce a multivariate score approach for summarizing confounding factors.

Main Methods:

Summarizing confounding factor patterns for each subject using a multivariate score.
Stratifying subjects based on their multivariate score.
Analyzing stratum-specific contingency tables using standard statistical methods.

Main Results:

The proposed multivariate score method simplifies the control of confounding.

This approach potentially increases the efficiency of etiologic research analyses.

Conclusions:

A multivariate score-based stratification offers a practical alternative to complex cross-classification methods.
This technique enhances the management of confounding in epidemiological studies.
