There is a report out today in The Lancet
(discussed here in the Guardian)
which attempts to measure the number of deaths from coalition actions in
"About 100,000 Iraqi civilians -- half
of them women and children -- have died in
A major story if true. One does not have to
be a partisan Democrat to "question the timing" of an announcement;
indeed one does not even have to be a potential voter in the US elections next
week to think that there is something a little, um, odd, about the timing of
this paper. For, as we are told:
"Last night the Lancet medical journal
fast-tracked the survey to publication on its website after rapid, but
extensive peer review and editing because, said Lancet editor Richard Horton,
"of its importance to the evolving security situation in
The full justification for the early
publication is given
by the Editor:
"Roberts and his colleagues submitted
their work to us at the beginning of October. Their paper has been extensively
peer-reviewed, revised, edited, and fast-tracked to publication because of its
importance to the evolving security situation in
"This political and military failure
continues to cause scores of casualties among non-combatants. It is a failure
that deserves to be a serious subject for research. But this report is more
than a piece of academic investigation."
More than a piece of academic investigation?
Really? Are we sure? We don't think that publishing this, in fact fast-tracking
it (A more normal "academic" paper would take up to six months to
wend its way through the peer-review process and the raw data for this was only
collected six and seven weeks ago.) has anything at all to do with an election
in the US some four days away? Good grief man, what do you take us for, morons?
At the very least one would have to add The
Lancet to that list of mainstream media which are worth 15% (or is it 5% now,
the left have never really been any good at numbers) to John Kerry in the
polls. What makes it a great deal worse is this, from the findings to the
report. In fact, these are the findings in their totality:
"The risk of death was estimated to be
2.5-fold (95% CI 1.6-4.2) higher after the invasion when compared with the
preinvasion period. Two-thirds of all violent deaths were reported in one
cluster in the city of Falluja. If we exclude the Falluja data, the risk of
death is 1.5-fold (1.1-2.3) higher after the invasion. We estimate that 98 000
more deaths than expected (8000-194 000) happened after the invasion outside of
Falluja and far more if the outlier Falluja cluster is included. The major
causes of death before the invasion were myocardial infarction, cerebrovascular
accidents, and other chronic disorders whereas after the invasion violence was
the primary cause of death. Violent deaths were widespread, reported in 15 of
33 clusters, and were mainly attributed to coalition forces. Most individuals
reportedly killed by coalition forces were women and children. The risk of
death from violence in the period after the invasion was 58 times higher (95%
CI 8.1-419) than in the period before the war."
Have a look at those confidence levels. Yup,
95%. That is, a one in twenty chance that the effect simply does not exist.
Look at the relative risk ratios (leave out Falluja; I don't think anyone is
really very surprised to see a higher mortality rate there): 1.1-2.3. It isn't
just that it is an absurdly wide one (note, a relative risk ratio of 1 would
mean no effect whatsoever) it is that if this paper was written to generally
accepted statistical standards it would never have been published. With a 95%
confidence level a relative risk ratio of anything less than three is regarded
as statistically insignificant. Just to clarify that, by
"insignificant" no one is stating that it is not important to those
people who undoubtedly have been killed during the War. What is being said is
that we don't have enough information to be able to say anything meaningful
about it. "Statistically insignificant" means "we don't
know".
In effect, what has been found in this paper
is nothing. Nada. Zip.
Except of course that one of the two leading
medical journals in the world has published a piece of shoddy research four
days before the US elections with the obvious motive of influencing them. Sad,
that, and my apologies as an Englishman that it should be one of my countrymen
who did such a thing.
