Text and Tables Not Matching
The report by Mr. Morgan and colleagues points out that the
abstract and conclusion section of the paper state there was
no "exposure–response" relation, and that "no increased risk
of brain tumors was observed for brain areas receiving the
highest amount of exposure," but this is contradicted by
data reported in the paper.
In Table 5, for example, data showed that when the duration
of the cell phone subscription was more than 4 years (the
highest exposure), there was greater than a 3-fold risk for
brain cancer (OR, 3.74). There was also close to a 3-fold
risk when the number of cell phone calls was greater than
2638, the highest exposure (OR, 2.91).
Of importance, there are discrepancies between the tables in
the paper and the text, which suggests that "the results may
be misleading," Mr. Morgan and colleagues write.
As an example, the text reports that 35% of cases and 34% of
control subjects had operator data since the start of their
subscription; if calculated out, that would mean that there
would be 123 cases and 200 control subjects with this
information, they note.
However, Table 4 reports 196 cases and 360 control subjects.
The reason for this discrepancy is unclear, "but it would
likely make a large difference in the associated risks as
there would be 37% fewer cases and 39% fewer controls," they
write.
An odd finding is that ipsilateral risk was smaller than
contralateral risk, which contradicts the findings of other
studies, the authors write. The most likely explanation is
that the reported laterality was not consistent with use.
Nevertheless, these results are of major concern, Mr. Morgan
and colleagues write.
More Research and Precautions Needed
"There is a great need for research, and we need more
precautionary messages," said Dr. Moskowitz. "I don't know
if we have enough science to come up with standards at this
point, but we have a fair amount of evidence for increased
brain tumor risk, as well as to the reproductive organs."
About a dozen countries have taken precautionary steps, so
it would "not be radical for the United States government to
do so as well," he said. No one is suggesting that we give
up cell phones, "but there are ways to reduce the risk."
