SAS宏程序在自动获得多于24小时动态血压监测整体谷峰比中的应用

Application of SAS procedures in evaluation of trough/peak ratio in ambulatory blood pressure monitoring

目的:为避免手动处理多于常规动态血压监测数据所造成的错误,采用SAS宏程序自动获得动态血压数据整体谷峰比。方法:使用SAS软件中相关语句自动生成处理多于常规动态血压监测数据的宏程序。结果:将原始数据输入SAS程序中,运行宏可以获得服药后24h内每小时的整体水平血压差值,并且最终得到试验组和对照组整体降压谷峰比。结论:利用宏程序可以处理超出药后24h的动态血压监测数据,并最终生成临床医师所需要的谷峰比。

AIM： To explore the SAS macros implementation of trough/peak in ambulatory blood pressure with different kinds of records. METHODS： Implying procedure retain, SQL and cycling do, create macro procedure output ring statistical analysis report forms. RESULTS： After checked data entered into the SAS proce dure, average difference of blood pressure values per hour in 24 hours after drug administration was created when running the macros. Thewhole trough/peak ratios oftreatment and con trol groups were finally calculated. CONCLU SION： Trough/peak ratio required by clinician could be obtained by using macros dealing with ambulatory blood pressure with records excee ding 24 hours after taking medicine.
