It is known that 20% of individuals chronically treated with digoxin suffer an adverse reaction due to it. Ten patients were given digoxin plus other medications for a long time, and 5 of them developed the adverse reaction. Can it be stated that the association between digoxin and other drugs makes the number of adverse reactions vary?
