I've taken a look and this is what I get.
Your blog premise is the JW death rate in New Zealand from anemia is 0.26/1000.
Quoted from your blog - " That is, the extrapolated annual rate of mortality for Witnesses who suffer death from severe anemia as a result of Watchtower’s blood doctrine is .026%." (0.26/1000)
and
"This study found 103 Witness patients who suffered severe anemia and 20.4% of these died. During this period the death rate among patients who suffered severe anemia but accepted ARBC transfusion was 1.9%."
In other words a JW with severe anemia (in New Zealand) dies at 10.74x the rate of the general population with the same condition. Are we in agreement so far?
The problem is that 0.26/1000 is a factor of 130x with the 0.2/100,000 anemia death rate for the general population in New Zealand according to worldlifeexpectancy.com. And yet according to the NZ study the variance is 10.74x.
So which is it? Are JW's 10.74x more likely to die from anemia or 130x more likely?
The next obvious questions for me are how many JW's have there been on average at any one time, and what is the typical death rate from anemia. If we know how many JW's are walking the planet in any one year, we can apply the anemia death rate and multiply that figure by 10.74 to extrapolate JW anemia deaths, based on the NZ study.
According to http://www.worldlifeexpectancy.com/cause-of-death/anaemia/by-country/ - New Zealand has 0.2/100,000 anemia death rate. The USA has 0.5/100,000. The UK has 0.1/100,000.
Lets use 0.75/100,000 to be generous and accounting for more recent growth in JW's in Nigeria, Brazil, Mexico etc. Multiply by 10.74. That gives a JW an anemia death rate of 8.055/100,000. That is - a JW with anemia is like a Rwandan with anemia - anyways.
Now how many JW's are there at any one time?
I'm going to use round figures:
1960's decade total - 10m 1970's - 20m 1980's - 30m 1990's - 45m 2000's - 65m
1960's = 10m * (8.055/100,000) = 805 JW's in the 1960's died from anemia.
Continue the maths and you get to total 13,700 JW's that have died from anemia for the 5 decades, globally.
Just a thought.
EDIT - I haven't subtracted the estimated number of those who would have died 'anyway'
