I don’t think the negative correlation between doctors and patients opinion of the drugs is surpassing.
Rat poison would probably get a low score from both doctors and patients. However, nobody is being prescribed rat poison as an anti-depressant so it doesn’t appear in your data. Why is nobody being prescribed rat poison? Well, doctors don’t prescribe it because they think its a bad idea, and patients don’t want it anyway.
In order for any drug to appear in your dataset somebody has to think it is good. So every drug should have net-approval from at least one out of the doctors and patients. Given this backdrop a negative correlation is not surprising.
