This would bring down the cases of Lyme among depressed patients to 0.295% = 1 in 338. This number is still pretty high. However, if we had 338 people with depression currently posting on Psycho-Babble, only 1 would require treatment for Lyme. We don't have 338 people posting on Psycho-Babble. If the numbers are off, they are not off by that much. They suggest that it is unlikely that even 1 person here has Lyme. It is important to take into consideration that the incidence of Lyme Disease varies greatly regionally, and that the population of Psycho-Babble is waited heavily towards treatment resistant depression.

I really made one calculation regarding Lyme Disease.
"Depression with Lyme = 0.295%"
"...the cases of Lyme among depressed patients to 0.295% = 1 in 338"
If I were to use the more liberal value, 66% instead of 26%, the number would still be around (1 in 100) rather than (90 in 100). I have no way of knowing the incidence of Lyme in treatment-resistant depression (TRD), but I imagine the numbers are somewhat higher.
On the other hand, according to the article, approximately 40% of people with Lyme Disease display some sort of psychiatric symptoms (including depression). I'm sure lots of people are waiting for an accurate tool for diagnosing Lyme Disease.
