I can't see the whole paper - but from the Abstract it looks asif they may be trying to do biology using multiple regression analysis instead of scientific control (such as stratified analysis - specifically, they need sampling methods aimed the creation of homogenous comparison groups, controlled for relevant confounders).
MR (if that's what they did) is a method ill-suited to the task, and could explain the lack of comprehensible conclusions...
