Are you saying that out of 80 hospitals, the four hospitals in the study treat 57% of the population? That would mean the other 76 hospitals treat 43% of the population. That doesn't make any sense to me, can you explain?
I would say that would be a big indicator that they are not at all equal and comparable as Marvin claims they are - the main hospitals are likely more specialist centers and so it could well be a similar situation to the article Barb posted about them getting the most challenging cases and so having a higher than ordinary 'bad outcome'.
I'd also be concerned that they did the study for 57% of the population ... why not the rest? How much extra effort would it have been? Were figures that gave the desired results cherry picked? Who knows, it's an easy way of getting the results you want to see and again, I'd point to it being the Institute for Blood Transfusion which doesn't sound independent at all.
Marvin built a calculator you know. Have you ever built a calculator? Mmm thought so.
Yeah, all this talk of calculators is worrying - so far I've seen nothing presented that equates to any sort of calculator / model or simulation beyond just a few basic and very simplistic calculations as you can do with a $3.99 calc bought from Walmart.
The issue to me is still the confusion between:
- JWs
- JWs who have refused treatment
- JWs who have refused treatment and died as a result
I have little confidence that the 3rd can genuinely be accurately identified as the conclusive cause of death from records but let's keep ignoring that elephant in the room for now and focus on the rest of the herd.
The 103 would be group number 2 above. The 19 would be a subset of that, group 3.
Marvin is erroneously taking the rates from group 2/3 and applying them to group 1 but we know that group 1 and group 2 are different and group 2 is always going to be a subset of group 1.
If the number of JWs treated was 1000 and 103 (~10%) refused blood and 19 of these died then the mortality rate for being a JW is 1.9% which would be the same as the regular rate. Yes, if you refuse treatment your mortality rate goes up but the figures for that can then only be applied to people who refuse treatment, not to all JWs.
Now, what percentage group 2 will be of group 1 will be impossible to say but is also going to be affected by what treatments are available and the rules for accepting those treatments.
I believe there probably was a window where the doctrine was strongly promoted and more dangerous because alternative treatments were less available and this would dramatically affect the figures for that time period.
The doctrine has been dramatically weakened to the point that it no longer has such an impact and also the advances in alternative medical treatments mean that the consequences are less likely to be as severe as death.
A true model would take all these changing factors at different periods combined with the population of JWs at each time into account.
As far as I can tell, this has not been done and claims of 'building a calculator' is just another attempt to stiffle criticism by a crude appeal to intellectualism.
For the reasons above I believe Marvins figures are likely to be wildly wrong or at least have such a low degree of confidence that they can't in good faith be promoted, certainly not as being 'conservative' figures as claimed (actually saying that the result has a high confidence / low margin for error!).
