Consider the scenario and state whether the variable in question is a confounder: a cohort study of the risk of liver cirrhosis among female alcoholics. incidence rates of cirrhosis among alcoholic women are compared with those among nonalcoholic women. non-alcoholics are individually matched to alcoholics on month and year of birth. is age a confounder in this study?

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
