For example: does having ICU level of care actually do people any good? If the survival of hospitalized patients who go to the ICU is 60%, and the survival of those who don't go to the ICU is 95%, a very simple minded interpretation would be that ICUs are no good and are actually harming patients. Of course, what's really going on is that doctors are sending patients to the ICU only if they look like they're in serious trouble and have a higher chance of dying in the first place. If you really wanted to find out if ICUs work, you'd have to do a randomized study - say anytime a doctor wants to send someone to the ICU, the study coordinator flips a coin and then either allows or prohibits sending them to the unit. (Of course, then you have to get informed consent from patients who are willing to sign up for a study that will randomize them to having or not having ICU availability; good luck getting people to sign up.)
In this case, the docs are more likely to give treatment A to a woman and B to a man, and within each gender patients who got treatment B were more likely to recover. If you ask the docs why they're doing that, they might be able to give you a good reason. (Maybe B is a better treatment for motion sickness but causes excessive facial hair growth?) So to answer the question posed of which treatment to select for the hospital - there's not enough information presented.
