SEX DIFFERENCES IN HYPERTENSION MANAGEMENT USING KAPLAN-MEIER & LOG-RANK TEST
Keywords:
hypertensive Management, Kaplan–Meier Estimator, Log-Rank Test, Gender Differences, Survival AnalysisAbstract
This study investigated gender differences in hypertensive management by employing Kaplan–Meier Estimator and Log-Rank Test methodologies. Data were collected from 300 hypertensive patients at Specialist Hospital Sokoto between 2015 and 2021. The Kaplan–Meier survival curves demonstrated that the median times to achieve optimal hypertension control were 43.43 months (3.62 years) for men and 37.76 months (3.15 years) for women. Despite these differences, the log-rank test revealed no significant differences in survival curves between genders (p = 0.259). These findings suggest that sex did not significantly influence the time to optimal hypertensive management in this cohort. The findings of this study underscore the need for further research with larger sample sizes to explore potential variations in hypertensive management across different demographics. The recommendations include personalized patient care strategies and continued public health efforts to ensure equitable hypertensive management
