Sas enterprise guide 6.1:independent groups comparison for nominal data

Objective:  to develop algorithm of independent groups comparison for nominal data of prospective non-randomized clinical trial AMIRI – CABG (ClinicalTrials.gov Identifier: NCT03050489) using SAS Enterprise Guide 6.1. Materials and methods.  Data collection was performed according to prospective non-randomized clinical trial AMIRI – CABG in Pavlov First St. Petersburg State Medical University, Saint Petersburg, Russia between 2016-2019 years with 336 patients. Patients were allocated into three groups of treatment. There is database which include following information: gender, myocardial infarction, stroke and postoperative bleeding. Comparison for nominal data (gender and incidence of myocardial infarction, stroke and bleeding) were calculated with SAS Enterprise Guide 6.1 software with Chi-squared test and exact Fisher test. Results.  There was developed algorithm of two independent groups comparison for nominal data. Conclusion.  Presented algorithm of data analysis allows to compare independent groups for nominal data.
