How do you interpret treatment response in the DISCOVER-2 Trial when patients were allowed to remain on up to 10mg of prednisone equivalent for disease control while on guselkumab?

If patients were on less than or equal to prednisone 10 mg, they could continue that in the background during the trial, but note that only 20% of patients were on prednisone, a much lower figure than a typical rheumatoid arthritis trial, which is consistent with the point that rheumatologists shy a...
