> This is why the paper presented does not support the claim that LDL is the sole source of heart disease

Is that what we were arguing about? I guess it was. At some point in thinking about this my frame must have shifted into agreement with you. Of course there are other causes of heart disease besides LDL, like blood pressure, duh. The smooth dose response is about the particular gene not being linked to heart disease through something other than LDL, roughly.
