In a screening of 1,000 individuals with 70 diabetes cases at baseline, what is the prevalence per 100?

Explanation:
Prevalence measures how many people in a population have the condition at a specific time. Here, 70 out of 1,000 people have diabetes, so the prevalence proportion is 70/1000 = 0.07. To express this per 100 people, multiply by 100: 0.07 × 100 = 7 per 100. So the prevalence per 100 is 7. The other numbers reflect different representations: 0.07 is the proportion (not per 100), 70 is the raw count of cases, and 0.7 would imply 70 per 100 (which would correspond to a much higher rate than the observed data).
