Hypothesis
Does low socioeconomic status (SES) increase mortality after first-ever ischemic stroke in China?
Conclusion
Lower SES negatively impacts the outcome of first-ever stroke in Nanjing, China.
Supporting Evidence
- Manual workers had a hazard ratio of 5.44 for death within three years compared to non-manual workers.
- Those in the zero income group had a hazard ratio of 5.35 for death compared to those in the highest income group.
- Lower housing space was associated with increased mortality, with a hazard ratio of 2.06 for those with the least space.
Takeaway
People with less money and education are more likely to die after having a stroke.
Methodology
The study used stepwise univariate and multivariate COX proportional hazards models to analyze the association between SES and three-year mortality in 806 patients with first-ever ischemic stroke.
Potential Biases
Potential selection bias due to the hospital-based nature of the study.
Limitations
The study is hospital-based, which may not reflect the overall conditions in China and could introduce selection bias.
Participant Demographics
Mean age was 71 years, with 31.9% being women.
