Abstract

Abstract: AIM: To explore the application of Bland-Altman in quantitative data consistency evaluation,and realize it with SAS macro. METHODS: According to the principle of Bland-Altman method and the steps of the consistency analysis, we wrote SAS macro command.RESULTS: The SAS macro could use the Bland-Altman method to evaluate the consistency of quantitative data, and output graph and table results of analysis into word, save a lot of time for clinical trial statistics. CONCLUSION: Consistency evaluation of quantitative data should use the Bland-Altman method, the SAS macro provided great convenience for the method, contributed to its popularization and application.

Key words: quantitative data, agreement assessment, Bland-Altman, SAS Macro
