AI Article Synopsis

  • The text emphasizes the importance of researchers in clinical trials to carefully evaluate when to use intention-to-treat (ITT) analysis versus per protocol analysis for accurate outcomes.
  • It highlights that while ITT analysis is generally recommended for assessing treatment adherence, it can be misused due to inappropriate questions being posed, misunderstanding noncompletion of treatment, and random assignment violations.
  • The authors suggest that future clinical trial designs, especially in child and adolescent research, will likely incorporate hybrid trial elements, merging efficacy, effectiveness, and implementation research, where both ITT and per protocol analyses will be utilized correctly.

Article Abstract

We call for clinical trials researchers to carefully consider questions about use of intention-to-treat (ITT) analysis and per protocol analysis. We discuss how questions about are appropriately answered through the application of per protocol analysis. ITT analysis is well-suited and appropriate for addressing questions related to treatment , typically adherence to the treatment with respect to an outcome. While guided by admirable intentions, ITT analysis is often not guided by the right questions, leading to ITT misapplication. We address additional misconceptions that often lead to ITT misapplication, including issues relating to treatment noncompletion and violation of random assignment. We further highlight future directions and implications, particularly that future clinical child and adolescent research trial designs will be increasingly characterized by hybrid trials that combine elements of efficacy, effectiveness, and implementation research, where ITT and per protocol analysis will be appropriately applied to answer the right questions.

Background: The effect of initial antiretroviral therapy (ART) class on cancer risk in people with HIV (PWH) remains unclear.

Setting: Cohort study of 36,322 PWH enrolled (1996-2014) in the North American AIDS Cohort Collaboration on Research and Design.

Methods: We followed individuals from ART initiation (protease inhibitor [PI]-, non-nucleoside reverse transcriptase inhibitor [NNRTI]-, or integrase strand transfer inhibitor [INSTI]-based) until incident cancer, death, loss-to-follow-up, 12/31/2014, 85 months (intention-to-treat analyses [ITT]), or 30 months (per-protocol [PP] analyses).

Background: Directly observed therapy (DOT) is the standard for monitoring adherence for tuberculosis (TB) treatment. However, the implementation of DOT is difficult for patients and providers due to a lack of financial and human resources. Mounting evidence suggests that emerging digital adherence technologies like video directly observed therapy (VDOT) can serve as an option.

Background: Cholelithiasis areis a common digestive system disorder, with cholesterol gallstones being the most prevalent type. Gallstones lead to many severe complications, posing a significant burden on global healthcare systems. Many studies have shown associations between biliary microbiota, gallbladder immune microenvironment, and gallstone formation.

Difference in Restricted Mean Survival Time (DRMST) has attracted attention and is increasingly used in non-inferiority (NI) trials because of its superior power in detecting treatment effects compared to hazard ratio. However, when treatment switching (also known as crossover) occurs, the widely used intention-to-treat (ITT) analysis can underpower or overpower NI trials. We propose a simulation-based approach, named nifts, to calculate powers and determine the necessary sample size to achieve a desired power for non-inferiority trials that allow treatment switching, in ITT analysis using DRMST.

Objectives: The aims of this systematic review were to estimate the success rates of root caries restorations, and to identify possible factors associated with the success of root caries restorations.

Data And Sources: Literature search was conducted in three databases, PubMed, MEDLINE and Web of Science to identify clinical studies reporting on the success of restorative treatment for root caries. Factors that may influence clinical outcomes of the restorative treatment were summarized and analyzed.
