Analysis reveals risk factors for cardiovascular survival in Nigeria, indicating alcohol consumption impacts outcomes.
This study examines the survival times of cardiovascular patients using Kaplan-Meier (KM) survival curves and the Cox Proportional Hazards model. Analysis of data from Barau Dikko Teaching Hospital, Nigeria, revealed shorter survival times among male patients and those consuming alcohol or smoking. KM curves and Log-rank tests identified significant risk factors such as high blood pressure and irregular pulse rates. Cox model hazard ratios highlighted alcohol consumption as the highest risk factor. These findings demonstrate the utility of non-parametric and semi-parametric models in identifying survival determinants among cardiovascular patients.
