 Standardised response mean (SRM) of the change in DAS28 (SRM DAS28) and the number of CD68+ macrophages in the sublining (SRM CD68sl) for the individual studies (t, interval between the first and second measurement; n, number of patients, TI, treatment initiation) and grouped for patients who received initiation of an active compound (n = 70) and placebo (n = 18). The solid line indicates the 0.5 SRM cut off point (moderate), the dotted line indicates the 0.8 SRM cut off point (high).
