Question: is this a 2) strong advice, 1) weak advice 0) no advice?

However, the differences in both HOOS and EQ-5D between the 2 approaches were small, and it can be questioned whether the differences are above the minimal clinically important difference (MCID) (Ehrich et al 2000, Roos and Lohmander 2003, Terwee et al 2009, Larsen et al 2010, Roos 2012, Coretti et al 2014).
