Do certain coat types get IVDD more?

I've been doing a little research into IVDD because I'm looking into the breed as a potential candidate for my next dog. I'm trying to understand whether IVDD actually differs between coat types. I've read that smooth-haired Dachshunds have the highest rate of IVDD, but I'm wondering if that's because they're the most popular variety.

Is there reliable information on whether smooth, long-haired, or wire-haired Dachshunds have different rates of IVDD? I'd be really interested to hear from owners who've had multiple coat types. Did you notice a difference in overall back issues?
