From: Popliteal plexus block compared with tibial nerve block on rehabilitation goals following total knee arthroplasty: a randomized non-inferiority trial

Figure 2

Non-inferiority plot showing the observed difference between popliteal plexus block (PPB) and tibial nerve block (TNB) in the achievement of rehabilitation goals (Numeric Rating Pain Scale ≤ 4 at rest, 30-meter walk with a walker, and ability to perform 90° knee flexion). The dashed line indicates the non-inferiority margin (Δ). The horizontal bars indicate the 95% CI difference between the PPB and TNB groups. P < 0.05 was taken to indicate statistical significance.
