The effect of power, significance level and effect size on sample size are discussed. Calculations of sample sizes for individual-based studies are modified for more complex trial designs by multiplying individual-based estimates by an inflationary factor.</p>","PeriodicalId":29974,"journal":{"name":"NSW Public Health Bulletin","volume":"23 7-8","pages":"142-7"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"30959335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The collaboration will develop a new strategic framework that will provide clear direction concerning how we address Aboriginal health in NSW. We have done this by seeking genuine engagement and partnership with Aboriginal people, organisations and communities. A phased approach has been used to develop the Plan.
