title: Analysis of data in nephrology. I. Choosing the correct statistical test: dichotomous variables.
abstract: This is the first of six articles describing how to choose the correct statistical test to look for relationships between two variables. All examples relate to clinical or laboratory aspects of nephrology. In this article the overall strategy is outlined, and examples are given of analyses of data where each variable can take only two values.
