51The following appeared in a medical newsletter.
"Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain. This hypothesis has now been proved by preliminary results of a study of two groups of patients. The first group of patients, all being treated for muscle injuries by Dr. Newland, a doctor who specializes in sports medicine, took antibiotics regularly throughout their treatment. Their recuperation time was, on average, 40 percent quicker than typically expected. Patients in the second group, all being treated by Dr. Alton, a general physician, were given sugar pills, although the patients believed they were taking antibiotics. Their average recuperation time was not significantly reduced. Therefore, all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment."
In the newsletter, the writer advocates that patients who are
diagnosed with muscle strain should be well advised to take
antibiotics as part of their treatment. To justify his advocation
the writer cites the hypothesis on secondary infection. And the
hypothesis has been proved by a study in which some patients ,taking
antibiotics and treated by a sports medicine specialized doctor ,
recover more quickly than others who take sugar pills and treated by
a general physician. However, I find the argument logically flawed in
several critical respects.
In the first place ,the writer neglects the fact that two groups of
patients are treated by different doctors .Dr.Newland who specializes
in sports medicine are of course more clinically experienced in
curing muscle injuries than the general physician Dr.Alton. He may
apply more efficient methods in the treatment leading to shorter
recuperation time. While Dr.Alton lacking relevant knowledge , may
use
general method not aiming directly at muscle injuries, so his
patients may recover slowly. This difference may play a significant
role in different tempo of the recuperation.
Secondly, the author doesn't provide the fundamental information on
patients in the study. Patients in Dr.Newland' group may be much
more healthier and robuster than others,thus it's easier for them to
recover.Or muscle injuries of them are less severe .So their
recuperation time is quicker .Probabilities also exist in the facts
that they have experience and knowledge ,so they can treat
themselves besides the doctor' help.Thus the advice is unsound
without these information.
Thirdly,the author unfairly rules out other possibilities leading to
the quicker recuperation of patients in Dr.Newland' group.Their diet
may be more healthy and rich in nutrition including
vitamin,protein,etc .It's also possible that their living conditions
are much better, hasting the tempo to recover. Good mood may as well
contribute to the quick recuperation rather than antibiotics for it
can bring about better appetite and sleeping. We are not convinced on
the advice due to these possibilities.
In final analysis,this newsletter contains several critical flaws
which render it unconvincing. To bolster his advice,the author must
make a study himself.In the study, two groups of patients must be in
the same conditions and doctor must be the same one who specializes
in sports medicine in two groups.Also the diet ,living conditions and
other facts that may hinder a correct judgment should be the
same. Only after this improved study can we conclude whether the we
should take the advice or not.
