The evidence of voice treatments on the maximum phonation time (\n MPT<\/jats:styled-content>\n ) was quantified using the statistical approach of a network meta\u2010analysis (\n NMA<\/jats:styled-content>\n ).\n <\/jats:p>\n <\/jats:sec>\n \n Data Sources<\/jats:title>\n Three databases and manual search from inception to November 2021 were evaluated.<\/jats:p>\n <\/jats:sec>\n \n Study Selection<\/jats:title>\n \n Studies were considered which were reports of randomised controlled\/clinical trials (\n RCT<\/jats:styled-content>\n ) evaluating the efficacy of a specific voice therapy treatment using\n MPT<\/jats:styled-content>\n as an outcome measure in adult participants with voice disorders. Studies were excluded if participants had been diagnosed with neurological\u2010motor\u2010speech disorders or who were vocally healthy. Furthermore, no medical, pharmacological, or technical instrumental treatments were used.\n <\/jats:p>\n <\/jats:sec>\n \n Data Extraction and Synthesis<\/jats:title>\n \n Preferred Reporting Items for systematic reviews and meta\u2010analyses extension statement guidelines were followed. Two reviewers independently screened citations, extracted data, and assessed risk of bias using\n PEDro<\/jats:styled-content>\n scale. Random effects model was used for meta\u2010analysis.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n We identified finally 12\n RCT<\/jats:styled-content>\n studies (treatment groups\n n<\/jats:italic>\n \u00a0=\u00a0285, and control group without an intervention\n n<\/jats:italic>\n \u00a0=\u00a062). Eight interventions were evaluated. The only effective intervention with a significant effect was vocal function exercises (\n VFE<\/jats:styled-content>\n ) (mean pre\u2013post difference 6.16\u2009s, 95% confidence interval, 1.18\u201311.13\u2009s).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions and Relevance<\/jats:title>\n \n VFE<\/jats:styled-content>\n effectively improved\n MPT<\/jats:styled-content>\n from pre\u2010 to post\u2010treatment in comparison with other voice interventions which were identified in the present\n NMA<\/jats:styled-content>\n . Further high\u2010quality intervention studies with large samples sizes, multidimensional measures, and homogeneous groups of dysphonia are needed to support evidence\u2010based practice in laryngology.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1111\/coa.14019","type":"journal-article","created":{"date-parts":[[2022,12,20]],"date-time":"2022-12-20T01:29:45Z","timestamp":1671499785000},"page":"130-138","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":45,"title":["The maximum phonation time as marker for voice treatment efficacy: A network meta\u2010analysis"],"prefix":"10.1111","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0086-8163","authenticated-orcid":false,"given":"Ben","family":"Barsties v.
