Dry runway. Interesting note in performance is the (no) use of reverse thrust. But to conclude, landing performance isn't usually the issue on narrow body aircraft.
There is another threat (impact rate of descent), and the question if you are in such time critical event you need to challenge that threat. In case of pressurization problems, you don't. You can fly safely, you just can't climb safely.
