Hi Kathleen,
You make valid assumptions, and that's exactly what they are expecting to find out, but a lot of data is needed to establish a correlation and that won't necessarily mean cause-effect.
There are many confounding aspects that could also explain the prevalence in men, one that springs to mind is the higher incidence of comorbidities like hypertension and diabetes in men.
Keep calm and be alert 🤪
