Values are the risk ratio 95% confidence interval (95%CI) of dichotomous outcomes (dislocation and intra-operative fracture) or the mean difference (95%CI) of continuous outcomes comparing surgical intervention in column with surgical intervention in row (reference). Values of diagonal line in square brackets are surface under the cumulative ranking curve area and probability of being best surgical approaches (highest HHS and low risk of dislocation, intra-operative fracture). HHS: Harris Hip Score; PA: Posterior approach; LA: Lateral approach; DAA: Direct anterior approach; 2-incision: 2 incisions approach; LMIS: Mini-lateral approach; DSA/SuperPath: Direct superior approach or Supercapsular percutaneously-assisted total hip; NR: Not reported.
