Hypothesis
What is the prevalence of blinding trachoma in the northern states of Sudan?
Conclusion
The survey findings will help plan and allocate resources for the elimination of trachoma in northern Sudan by 2015.
Supporting Evidence
- Trachoma prevalence was above 10% in three districts.
- TT prevalence among adults was above 1% in 20 districts.
- Overall response rate was 81.6%.
Takeaway
The study looked at how many people in northern Sudan have a serious eye infection called trachoma, which can cause blindness. They found that many people need help to avoid going blind.
Methodology
Population-based cross-sectional surveys were conducted in 88 localities using two-stage cluster random sampling.
Potential Biases
Potential bias due to higher absence rates of adult men during surveys.
Limitations
The desired sample size was not achieved in 32 localities, and some areas could not be surveyed due to security concerns.
Participant Demographics
Mean age of participants was 20.9 years, with 42% male.
Statistical Information
Confidence Interval
95% CI for TT prevalence estimates ranged from 26,125 to 36,955.
