Methotrexate & liver fibrosis study

The quality of included studies was weak and the degree of selection bias means the results are not generalisable to all patients with psoriasis taking methotrexate.

Doesn't this, in human language, mean that in fact the study is quite worthless?

In some-ways yes, but some would argue any study is worth it. For example if we had a survey on how often you & me agreed, I would say around twice a year. You on the other hand would say never, so that gives an average of once per year which make me right more than you.

I don't agree.
Never times anything is always never.
