Network geometry. Network of all the included treatment modalities; the size of the nodes is proportional to the number of patients randomized to each modality and the thickness of the lines (edges) to the number of direct comparisons. Green lines indicate overall low risk of bias in the comparison, while red lines indicate high risk of bias. AA = auricular acupuncture; ACB = adductor canal block; ACB/S = adductor canal block plus sciatic; EA = epidural analgesia; F = femoral nerve block; FIC = fascia iliaca compartment block; F/O = femoral nerve plus obturator nerve; F/S = femoral nerve plus sciatic nerve; F/S/O = femoral plus sciatic plus obturator; ITM = intrathecal morphine; LB = liposomal bupivacaine infiltration; LP = lumbar plexus (psoas) block; LP/S = lumbar plexus (psoas) plus sciatic block; O = obturator nerve block; PA = periarticular infiltration; PCA = patient-controlled analgesia; Placebo = placebo (systemic opioids).
