### HideShow timer Statistics

Of patients over 65 years old who survived coronary bypass surgeryâ€”a procedure widely prescribed for people with heart diseaseâ€”only 75 percent benefited from the surgery. Thus it appears that for one in four such patients, the doctors who advised them to undergo this surgery, with its attendant risks and expense, were more interested in an opportunity to practice their skills and in their fee than in helping the patient.

Which of the following, if true, most seriously undermines the argument?

A. Many of the patients who receive coronary bypass surgery are less than 55 years old.

B. Possible benefits of coronary bypass surgery include both relief from troubling symptoms and prolongation of life.

C. Most of the patients in the survey decided to undergo coronary bypass surgery because they were advised that the surgery would reduce their risk of future heart attacks.

D. The patients over 65 years old who did not benefit from the coronary bypass surgery were as fully informed as those who did benefit from the surgery as to the risks of the surgery prior to undergoing it.

E. The patients who underwent coronary bypass surgery but who did not benefit from it were medically indistinguishable, prior to their surgery, from the patients who did benefit.

I would go with answer E here because in E it was clearly mentioned that doctors couldn't medically indistinguish between the patients who benifitted and patient who didn't benifit.

So doctors didn't recommend the patients to go for surgery for the sake of money.

What is OA?

E. The patients who underwent coronary bypass surgery but who did not benefit from it were medically indistinguishable, prior to their surgery, from the patients who did benefit.

I would also go for E.

The argument says that : For the patients of 65+ old, only 75% benefited. Hence for 25% times, doctor did not gave them proper advice that surgery might not be beneficial to them.

E says that before surgery, the patients were in same medical condition. Hence if the surgery worked for 75% people, it should have worked for 25% also. This sentence properly undermines the argument that doctors gave wrong advice.

Both D and E undermine the argument. But IMHO E states a stronger reason.
In D, doctors did their job of informing the patients.
IN E, doctors did not or could not have a self motive because the patients who could benefit and who could not benefit were medically indistinguishable

The flaw with D here is that the patients were fully informed but of what ..?? were they informed that surgery would beneficial to them ? But was the surgery needed for them ? Hence D does not do job properly or as better as E.

I have been stuck upon between 2 options D & E.
But eventually I 've selected D.
My reasoning is:
In the text,the doctors are considered blameworthy since they are supposed to advice the particular mode of surgery for professional gain.Only the option D weakens the above supposition,roundly and squarely.Option D points a doubt that risk involved in this mode of surgery were fully explained to all the patients by the doctors.So, D is more appropriate ans than E.
The idea behind the term, 'medically indistinguishable' is a vague one.It covers a no of issues.Moreover, the option E fails to establish that the doctors concerned were not worthy of blame.So, this particular option simply does not fill the bill.
Why official ans is E.

Choice D means that the patients were fully informed, but this information is irrelevant to the argument. This choice doesn't affect the argument that the doctors were more interested in an opportunity to practice their skills and in their fee than in helping the patient.

In choice E, since we cant distinguish between patients who did benefit and patients who didn't, there is no reason to blame doctors.

+1 E.

The author voice his/her concern from the Doctor's perspective over the failure rate.Choice E exactly undermines that by saing Doctors can not dishtinguish between the petients.

Choice D,on the other hand,adresses the petient's point of view,which is irrevalent.

Choice D - Patients were aware of the consequences of the surgery before hand and still opted to undergo the operation -> Doctors less culpable.
Doctors' motive might have been practice/fee but ultimate decision making power was with the patients.

Choice E - Before surgery patients were medically indistinguishable but we do not know if doctors were forthright in conveying surgery associated risks to them -> Doctors may or may not be culpable.

Experts help plz.

Consider D. Assume that the patients were told about the risks but if the doctors could identify the ones who would not survive then the doctors would practice on these patients and still get a good success rate by operating on the ones they are sure to survive. This cannot weaken the argument. This thought leads us toward E.

For me, this just came down to "D" and "E". The other A/Cs I thought were clearly insuff.

Between "D" and "E", for me, it was the case of "which is the crappier answer"? This is where "D" won.

D. The patients over 65 years old who did not benefit from the coronary bypass surgery were as fully informed as those who did benefit from the surgery as to the risks of the surgery prior to undergoing it.
--> if all patients undergoing the surgery well fully informed of the risks, how does this impact bias? if any case, this is an OPPOSITE/STRENGTHENER. hear me out: if the doctors are telling each patient that there are risks, then how could there be bias? this leads me to believe there was no bias, everyone was treated the same.

E. The patients who underwent coronary bypass surgery but who did not benefit from it were medically indistinguishable, prior to their surgery, from the patients who did benefit.
--> on the other hand, if the patients could not be distinguished, how would the bias work? which groups of people would the doctors discriminate/hold bias against? this WEAKENS.

kudos if this helps
