Testing screen width....and can I post this?

TaxGuy, these figures, from the BMJ, show that the amount smoked is highly relevant. If I’ve iinterpreted them correctly, you can see from the line in bold the great increase in going from no cigarettes to 1-14/15-25/>25 cigarettes per day. I suppose it’s possible that 1-14 does not apply to ten or less, but I don’t think so (although this doesn’t seem to be specifically addressed in the study as far as I can tell.).
I so hope this doesn’t screw up the screen for everyone. I’m going to email the mods in case it does.

 If smoking is unrelated to mortality from a particular disease the
standardised trend test has expectation zero and a standard deviation of
unity, so values above 1.96, 2.57, and 3.29 correspond to P values (two
tailed) of 0.05, 0.01, and 0.001.

Aw crap.
Mods, I took this from a BMJ article.
I’m not sure if I may have reproduced too much…?
Can I leave it here and link to it to avoid screwing up the width in the thread?

Interesting,
your odds of getting liver cancer or leukaemia seem to go down with about one pack a day verses never having smoked.

4

whuck: I’d call that statistically insignificant for two reasons: First, only 66 people in the survey had it at all. Second, it’s only a drop of one case. Small sample size + Tiny variance = Nothing worth calling correlation, let alone causation.

5

Bah. I didn’t see non-myeloid leukaemia and ignored your reference to liver cancer.

And I completely misinterpreted the survey.

I need to get more sleep.

I’m gonna leave it, but just for the record, wide posts like that really annoy me. Hope you didn’t post it elsewhere on the board like like that.

Yeah, sorry Tuba, I didn’t think it’d be that (ridiculously) wide.
I found a much abbreviated version for the thread.
Thanks anyway.
