Anti‐TNF disease activity–guided dose tapering vs anti‐TNF continuation

Number of serious adverse events · people with rheumatoid arthritis with low disease activity using a standard dose of anti‐TNF agents

It is very uncertain whether anti‐TNF disease activity–guided dose tapering changes number of serious adverse events compared with anti‐TNF continuation (very low certainty).
