At the initial examination of a prospective cohort study initiated in 2012, diabetes was found in 20 per 1,000 men aged 40-60 yrs of age and in 20 per 1,000 women in the same age group. After 7 years of follow-up of the study participants free of diabetes at baseline, the incidence of diabeteswas found to be 4 per 1,000 in men and 5 per 1,000 in women in the study cohort. Assuming no influence of other external or confounding factors, the inference that in this age group men and women had an equal risk of developing diabetes is:

A.Incorrect because based on the data provided women are more likely to develop diabetesthan men

B.Incorrect because based on the data provided men have a higher incidence of diabetes than women

C.Incorrect because there is no control or comparison group

D.Correct
