Looks like I have one more post…
“What this thread does show is that, contrary to Mr. Shilmer's contention, Ms. Barrick's tweet was horribly irresponsible because her contention is so easily attacked.”
The single thing of assuming deaths at all trauma centers in New Zealand are on par with the 4 whose data was mined by Dr. Beliaev et al would push the statistical number of deaths among JWs for refusing blood between 1961-2011 to over 200,000.
- That statistical increase would still not include a higher mortality rate due to Watchtower’s pre-2000 tighter restriction on blood products.
- That statistical increase would still not include a higher mortality rate due to a higher historical dependence on blood transfusion in patients with severe anemia (before products like EPO et al).
- That statistical increase would still not include higher mortality rate due to healthcare systems less equipped than found in New Zealand during years 1998-2007.
The only thing I find disturbing about the 250,000 number is that it was not offered along with a solid means to examine it for veracity by its author. Rightly that deserves criticism. On the other hand, I’ve observed skeptics in this discussion criticize on a basis of statistical hogwash. Anyone who wants to engage this subject on substantive grounds should undertake a careful analysis to find hard and reliable numbers useful as a population within a given sample. Then they should present this data and express in concise mathematical terms their conclusions. So far the only data collection I’ve seen offered comes from Dr. Beliaev et al, and it appears as though I’m the only person who actually read the collection.
“Does it say if it was done 'blind'? i.e. were unidentifiable patient outcomes compared and then the groups identified or were they put into groups and then the outcomes compared? One is open to considerable bias whether consciously or not.”
You can’t do a blind matched set data collection. To achieve a matched set you have to examine all records in a given patient population and let the sets align to given criterion. In this case the given patient population was all admissions to 4 particular hospital within the New Zealand healthcare system.
“Still, given the interest in the outcome by the people conducting the study and the miniscule size of the data-set, even if the study was well conducted I think there are question marks over what can be interpreted by it (beyond 'getting medical treatment is a good idea') and we're still left with the problem of how that is extrapolated out to a much larger population.”
This is an aspect of Dr. Beliaev et al’s data collection and analysis that is noteworthy: the review was not to figure out mortality but, rather cost effectiveness of treatment options. The authors were not mining for or against a particular finding of mortality due to refusing blood. It just happened to be that a mortality statistic lept from the data collection that deserved exposure.
The “problem” of extrapolating the larger picture from this data set is not a problem. It’s simple math. What’s important is that the math is properly done to let values speak for themselves. In my case I held to a very conservative extrapolation for greater veracity.
“You didn't answer my question about the number of witnesses in NZ: If instead of 12k the WTS had either 10k or 20k members, would the deaths of 19 out of 103 anemia patients result in different figures using your methodology? If it would then your methodology is faulty.”
I don’t understand what you’re talking about. Were the number of JWs in New Zealand less than 12,000 and the same number died due to refusing blood then the extrapolated number of 50,000 deaths would be larger than 50,000. Were the number of JWs in New Zealand greater than 12,000 and the same number died due to refusing blood then the extrapolated number of 50,000 deaths would be lesser than 50,000. That is how math works.
It is absurd for anyone to think that different values arrived based on different inputs means a value is right or wrong. That said, different inputs typically will result in different values!
As it is we know the number of JWs in New Zealand for the years in question and we have data telling us the number of JWs who died preventable deaths in the same demographic. From that point it’s only a matter of doing the math and letting these inputs speak for whatever they say.
