A member asked:

I see many places say 30% of people with psoriasis develop psoriatic arthritis. but then when i actually read studies several large scale investigation only show 5-20% do. thats a big difference so why do many places still say 30%?

A doctor has provided 1 answer

In some cases people develop the arthritis before the skin eruptions of psoriasis actually appears. I wonder if some of the studies include these type of cases retrospectively while other studies hadn't included them.
