Why doesn't the absence of "lead is good" data simply mean that your model is flawed?

Yes, that is one possibility. Not all distribution have an inverted ʃ shape in this graph. In particular, the exponential distribution is very different and very asymmetric, but nobody expect an exponential distribution in a group of studies like this.

Also, "my" model is an informal version of the model used in the research paper. You can read there an explanation with more technical details and more accurate.
