1.Two groups of patients were chosen in order to compare a new treatment with a standard treatment. One group of patients received the new treatment and one group received the standard treatment. Some patients in each group had an adverse outcome and some patients in each group had a good outcome. Given the following data:

Number of patients (total) = 4,697

Number of patients who had an adverse outcome with the new treatment = 168

Number of patients who had an adverse outcome with the standard treatment =205

Number of patients who had a good outcome with the new treatment =2,257

Number of patients who had a good outcome with the standard treatment =2,067

a.Construct, label, and completely fill in a 2 x 2 decision table that accurately reflects the data (10 points)

The 2x2 Table - Treatment Outcomes

***My table will not copy and paste but IS THIS CORRECT ORDER FOR A,B,C,D,?***

A =New treatment with adverse outcome

B= Good outcome new treatment

C = Standard treatment adverse outcome

D = Standard treatment good outcome

b.Calculate the relative risk of an adverse outcome for the new treatment.Show all work!(5 points)

RR = [a/(a+b)] / [c/(c+d)]

= [168/(168+2,257)] / [205/(205+2,067)]

= [168 /(2,425)] / [205 / (2,272)]

= 0.07 / 0.09

= 0.777

= 0.78
