Abstract
Background:
Computer use has lead to a great development of statistical methods.
Aim:
To assess the use of statistical methods in Chilean medical literature.
Methods:
Two hundred sixty four papers appeared in Revista Médica de Chile and Revista Chilena de Pediatría between 1983 and 1993 were reviewed.
Results:
Student's "t", Fisher's, and chi 2 test are the most frequently used statistical methods in 67% of papers. Correlation coefficients are used in 10% of papers. Multivariate methods are seldom used.
Conclusions:
Statistical analysis of papers published in Chilean medical journals is restricted to very few methods.
