Hey lads
So more than once i’ve done basic arithmetic in my head instantly with no process to calculate it. Small sums like 16 + 36 and my mind would instantly get the right answer. This has happened often; sums I would have to actually process before saying an answer. But it seems sometimes i can just blurt out the answer and it’s right… Any explanation for this?

Im reading this research paper about certain antidepressants having a possibly very positive outcome on the physical implications of a cov infection. [since the filter flags the url /doi I will put it in the first reply
and there is this statement at "Study endpoint":

following adjustments, the primary multivariable analyses with inverse probability weighting showed significant associations between use of any antidepressant (HR, 0.56; 95% CI, 0.43–0.73, p<0.001) (Fig. 2), SSRI antidepressants (HR, 0.51; 95% CI, 0.316–0.72, p<0.001), and non-SSRI antidepressants (HR, 0.65; 95% CI, 0.45–0.93, p=0.018) (Fig. 3)

What do HR <value> and Cl <value> mean. I saw this popping up earlier in another paper that was send to me but I can't make sense of these values/handles. Like what do Cl,Hr mean. It has something to do with the probability I guess but im not sure. Not asking anyone to do my homework, I just want to be able to actually make sense of the things I read here because just looking at the abstracts is "lamo >Science dude" bullshittery. So yeah would be nice if someone could give me a hint here.

there's no number between .999... and 1, so .999...=1.
but there also isn't any number between .999... and .888..., so .888...=.999...
repeat the process with other numbers and you'll see that any number is equal to any number.
there, I broke math
