Question

I.S. Wright and associates did a clinical trial on the effect ofanticoagulant therapy for coronary heart disease. Eligible patientswho were admitted to participating hospitals on odd days of themonth were given the therapy; eligible patients on even days werethe controls. In total, there were 580 patients in the therapygroup and 442 controls. An observer says, Since the odd-even assignment to treatment or control isobjective and impartial, it's just as good as tossing acoin. Do you agree? Explain briefly. (Assume trial was done in amonth with 30 days)
I think I would disagree with the observer (it seems likethere are a lot more controls than people who were giventreatment..) but I'm not sure.
Any suggestions would be greatly appreciated! Since the odd-even assignment to treatment or control isobjective and impartial, it's just as good as tossing acoin. Do you agree? Explain briefly. (Assume trial was done in amonth with 30 days)
