Is There a Cross Over Effect?

There's too much variability right in the middle. Could explain some cases of cids, for example, but not all. It could be a good place to continue with the research. Let's collect more data. Let's start to understand exactly what's going on. Is that, unfortunately, it's pretty well accepted that sids is not one thingad. It's a multi factorial. Soe, there are probably multiple causes for this. We're nowhere near that.
