>But after the researchers adjusted for factors including parental ages and maternal smoking status, they found a 3.39-fold rise in the odds of a genital defect

If they didn't adjust for obesity, then it's really pointless to attribute this to the drug. Age and smoking status is not enough.

Why would you assume they didn't? They most likely did.

From the quote it says they only adjusted for age and smoking.

I did indeed not read that properly. I'd have to check the actual publication. It's at least suspicious that they don't mention it, since obesity is probably the first thing you should think of when saying diabetes.
