Dear all,

I want to compare  two proportions of  disease in two populations : group 1 (1200/15000) and group 2 (260000/6500000). However  I would take into account the number of physicians involved in each group G1 (1600 physicians) and G2 (1.6 million). Please can someone can help me ?

 

Thanks
