This month’s contribution comes from Sinziana Oncioiu, who is a public health researcher affiliated with Karolinska Institutet in Stockholm, Sweden. In this article, she will provide an in-depth delineation of her research which she presented at the EUSPR conference in Ljubljana in 2015. Her research targets complementary analyses to intention-to-treat analysis in an effectiveness study that was conducted at Karolinska Institutet.
At the 6th annual conference of the European Society for Prevention Research (EUSPR), I had the chance to present the results of my Master’s thesis. Its focus was on alternative methods to intention-to-treat (ITT) for a better understanding of the effects of interventions evaluated using randomized controlled trials (RCTs). The data I worked with came from the FRITT study which stands for “Free from tobacco in dentistry”. It is an RCT designed to evaluate the effectiveness of a brief counselling on tobacco cessation in dental clinics in Sweden1. The ITT analysis showed that the brief advice was effective in reducing the amount of tobacco used at baseline, but not in achieving abstinence1. In this post, I will walk you through the main lessons learnt during this study. Continue reading
