  "abstract": "Introduction Approximately 20%–40% of older adults face loneliness. The effectiveness of artificial agents used to treat loneliness in this population is contentious in current studies. We aim to investigate the efficacy of this treatment for loneliness and other well-being outcomes in the elderly and identify factors that moderate its effects.Methods and analysis A systematic review and meta-analysis of randomised controlled trials and non-randomised studies of interventions with control groups involving artificial agents to alleviate loneliness in older populations; data sourced from PubMed, CENTRAL, EMBASE, CINAHL (EBSCO) and PsycINFO (EBSCO). Two reviewers will independently assess the literature, with a third reviewer consulted to resolve disagreements. Study characteristics will be narratively summarised. A meta-analysis will assess treatment effects on loneliness and other outcomes. Meta-regression and subgroup analysis will be conducted based on artificial agent type, treatment strategy and participants’ settings; and comparisons performed via a random-effects model, using Cochrane Review Manager V.5.4.1 and STATA V.16.0 for quantitative synthesis. Study quality will be assessed using appropriate risk-of-bias assessment tools. Cochran’s Q test and I 2 statistics will assess heterogeneity. Publication bias will be identified using Egger’s test and a funnel plot.Ethics and dissemination Since this systematic review is carried out based on published scientific databases, it is exempt from ethics approval. The findings of this review will be disseminated in a related peer-review journal.PROSPERO registration number CRD42023428127.",
