Association of Sleep-Disordered Breathing, Sleep Apnea, and Hypertension in a Large Community-Based Study; F. Javier Nieto, MD, PhD et al; JAMA, Vol. 283 No. 14, April 12, 2000
This is the definitive study on the connection between sleep apnea and hypertension. There is no doubt as to a connection after this study. And it ties the RDI to increased risk. FYI, weight is factored out.

I don't recall the study, but it came out 3 to 4 years ago tying sleep debt to traffic accidents. In plain English, there are more traffic accidents caused by sleep debt than alcohol. And sleep apnea is a major cause of sleep debt.
Another interesting point, a well rested individual will have the same cognitive functions and response time as an individual with a .5 to .8 blood alcohol level after 17 hours without sleep.
I have never seen anything saying that CPAP is ineffective for people with an RDI less than 30. Where have you read/heard this? Insurance companies and medicare care are paying at a lower level than this.
There is a follow up study to the one I named at the start. It is investigating the effectiveness of CPAP in reducing blood pressure in people with sleep apnea and hypertension. It should be noted that these are large scale, long term studies. The type of definitive work we need for more recognition of sleep apnea.
