I see, thanks! So those are the hazard ratios for each of the segments of consumption of coffee, right? (5 coffee drinking segments, 5 hazard ratios)

  Correct, ">3.5 to 4.5" / "0.71 (CI, 0.60 to 0.84)" means "we're 95% confident that people who had 3.5 to 4.5 unsweetened coffees per day had 60-84% the risk of mortality of baseline (average 71%)".

    Ohhhhh, thank you! That makes sense. It seems there was an implicit assumption of 95% (p<0.05), is that right?

      Right. 95% is the most common threshold for a CI.
