Tardive Dyskinesia (TD) can occur in people exposed to dopamine receptor antagonists (DRAs). Its clinical management remains challenging. We conducted a systematic review/random-effects network meta-analysis (NMA) searching PubMed/MEDLINE/PsycINFO/ClinicalTrials.gov/Cochrane Central Register (22/05/2023, pre-defined protocol https://osf.io/b52ae/ ), for randomized controlled trials (RCTs) of pharmacological/brain stimulation interventions for DRA-induced TD in adults with schizophrenia or mood disorders. Primary outcomes were TD symptom change (standardized mean difference/SMD) and all-cause discontinuation (acceptability-risk ratio/RR). Sensitivity analyses were conducted. Global, local inconsistencies, risk of bias (RoB-2 tool), and confidence in evidence (CINeMA) were measured. We included 46 trials (n = 2844, age = 52.89 ± 9.94 years, males = 59.8%, schizophrenia = 84.6%, mood disorders = 15.4%), all testing pharmacological interventions versus placebo. We identified three subnetworks. In network 1, several treatments outperformed placebo on TD symptoms with large effect sizes (k = 34, n = 2269), encompassing 22 interventions versus placebo, but 18 had 1 RCTs only, and 15 had n ≤ 20. High heterogeneity (I
