However, this difference did not reach statistical significance and is unlikely to represent a clinically meaningful improvement given the magnitude of effect and the high degree of heterogeneity. 3.4.1.1.1 VAS with disc displacement In patients with temporomandibular joint disc displacement 13 studies [18] , [22] , [23] , [28] , [30] , [31] , [33] , [35] , [37] , [38] , [41] , [43] , [47] , no statistically significant difference was observed between arthrocentesis and comparator interventions (MD = −0.79; 95% CI: −2.10–0.51).
