A large review of 142 individual studies analyzed the prevalence and incidence of multiple sclerosis (MS) in Iran. The study looked at how many people have the condition and how many new cases appear each year, specifically comparing data between men and women.
The findings show that the overall prevalence of MS in the region is 33.7 per 100,000 people. However, the data shows a notable difference between genders. The prevalence for women is 76.0 per 100,000, while the prevalence for men is 23.8 per 100,000. The annual incidence of the disease is 4.2 per 100,000 people.
Most importantly, the data shows a statistically significant upward trend in both the prevalence and incidence of the condition over time. Because this is a large review of existing studies, it provides a broad look at regional trends. These findings help health officials understand how the condition is spreading and changing in the population.
