| This slender volume was compiled through the joint
efforts of Guna S.r.l., Italy’s largest homeopathic pharmaceutical
company, and AIOT (Associazione Medica Italiana di Omotossicologia),
a professional medical association - Italy’s largest such
association for nonconventional physicians. Published in 2002 in
English and Italian, a revised and updated Italian Second Edition
has recently appeared; the English version has not yet been updated.
The authors of this volume identified roughly 400 studies of homeopathic
efficacy published up to December 2001. From this number, a final
roster of 127 studies was selected for review, excluding papers
that failed to meet established standards for systematic trials.
Excluded were studies that: did not permit treatment/trial outcomes
to be specifically correlated to the homeopathic intervention (as
opposed, for example, to other treatment interventions introduced
simultaneously); retrospective studies; lack of homogeneity of the
disorder(s) being investigated; small number of trial participants;
and methodological inadequacies.
Of particular interest to the Classical prescriber, the editors
of this volume observe that most controlled trials to date have
tested efficacy of homeopathic drugs in treatment of specific (allopathic)
diseases. Another increasingly important group of trials they identify
are those comparing homeopathic and allopathic medicines, many of
which have shown homeopathic remedies to be equal or superior to
conventional medicines. In addition to these more or less traditional
clinical efficacy trials, the editors of the present volume selected
65 papers representing findings in basic research regarding action
of homeopathic medicines.
For the most part, this book represents a kind of hybrid, mixing
features of the annotated bibliography with features of a meta-analysis.
It has gathered together those studies that meet accepted methodological
standards in research in controlled and systematic trials, as well
as in basic research, and discussed the overall positive implications
of the research findings from across this wide range of studies.
In addition, it provides basic bibliographic and substantive information
concerning each paper included within its covers. The editors have
also selected 10 papers they deemed especially significant, and
have provided a more detailed outline of their contents.
In short, this volume neatly encapsulates the field of research
into homeopathy, clearly demonstrating the scope and variety of
research activity, the recent trend to an increasing interest in
the subject within the scientific community, and the clear tendency,
across a large body of research, to supporting the notion of efficacy
of homeopathic treatment.
In these regards, this book contributes a well organized, concisely
presented overview of contemporary research – though one that
is in need of being updated, to reflect not only new research conducted
in the nearly 5 years since it’s publication, but also to
reflect the appearance of new meta-analyses that have in some cases
modified or even reversed positive findings from earlier meta-analyses.
In addition, the next edition would benefit from inclusion of even
more detailed analysis of selected studies, or more detailed statistical
analysis of trends within the body of cited research papers as a
whole. In this connection, the current reliance on a schematic summary
of trial designs and outcomes, while offering a more detailed picture
of these trials than we often get in a meta-analysis, in the end
leaves the reader hungry for a more substantive description of clinical
findings.
Admittedly, adding this sort of material would considerably expand
on the objectives of this work, and in that regard is more a recommendation
for a different book than a criticism of the present one. Nevertheless,
without such enhancements, we are left pretty much where we have
been for some time now, one side claiming the evidence favors them,
and the other side claiming the evidence is flawed. At the least,
others interested in homeopathic research should approach this volume
as a resource upon which to build, rather than a final summation
of the subject - indeed, it was a specific hope of the editors that
this compendium might serve in the role of such a foundational effort.
In any case, in this respect, as in so many others, an analytical
(clinical) approach can shed light, by detailed weighing of strengths
and weaknesses of specific trial reports. By comparison, this volume
leaves us in the usual quandary, relying too exclusively on statistical
analysis, which permits us to say with “certainty” only
that there is such and such “probability” that the whole
body of research supports this or that tentative conclusion. Unfortunately,
in such a process, compelling evidence of efficacy is ignored, as
I have previously argued (review of "The Trials of Homeopathy",
Homeopathy
4 Everyone, April 2006); conversely – as shown in Vithoulkas’
paper, reprinted elsewhere in this issue – such a process
encourages naïve acquiescence in the purported objectivity
of numbers.
That which the therapist calls “case review” is the
same as that which the statistician calls “nitpicking.”
Both processes explore the information and data included in a published
report, and analyze it, in accordance with standards appropriate
to the respective disciplines, to ascertain the soundness of the
project. In this regard, “nitpicking” is the application
of critical reason to evaluation of quantitative data, and represents
almost a “clinical,” and certainly an “individualized”
assessment of the heuristic value of the particular document: in
short, the fact that numbers add up the same way, regardless who
punches the keys on the keypad, doesn’t guarantee that the
right numbers have been found in the first place.
In research as in medical practice itself, statistics has nothing
whatsoever to say about the individual case (or trial) report –
a fact with which not even the most fanatical statistician would
argue. But perhaps it is time we grow up as scientists, and underscore
the importance of evaluating the quality of the individual case
(or trial) report, rather than settling for the pointillistic impressionism
of so-called “systematic” research. Perhaps it is time
we put an end to the obscurantist tendencies inherent when we apply
probabilities to practice, and demand that now, finally, we turn
our attention to identifying the facts that lay behind
the numbers.
