In many randomized clinical trials, assessment of safety relies on so-called on-treatment analysis, where data on adverse events are collected only while the participant is taking study medication and perhaps for a few (7, 14, or 30) days after stopping.
What is an n of 1 company?
N-of-One is a molecular decision support company providing clinicians with the most concise, accurate and clinically meaningful interpretation of molecular test results.
What is ITT population?
In a randomised trial, the set of all randomised patients is known as the ‘intention to treat population’, or the ITT population. This clinical trial study population is intended to represent suitable patients and to be reflective of what might be seen if the treatment was used in clinical practice.
What is on treatment?
This analysis is known as an “on-treatment” or “per protocol” analysis. A per-protocol analysis represents a “best-case scenario” to reveal the effect of the drug being studied. However, by restricting the analysis to a selected patient population, it does not show all effects of the new drug.
What is on treatment population?
In an ITT population, none of the patients are excluded and the patients are analyzed according to the randomization scheme. In other words, for the purposes of ITT analysis, everyone who is randomized in the trial is considered to be part of the trial regardless of whether he or she is dosed or completes the trial.
How many crossovers may be performed in a N-of-1?
Lobo and colleagues suggest a minimum of four treatment periods (i.e., two pairs or therapy randomized) to allow for at least three crossover comparisons [6]. This is consistent with a number of published N-of-1 trials which include three pairs of therapy randomized or six treatment periods [4,7,[17], [18], [19]].
What is mITT in clinical trials?
To address some of these issues, many clinical trials have excluded participants after the random assignment in their analysis, which is often referred to as modified intention-to-treat analysis or mITT. Trials employing mITT have been linked to industry sponsorship and conflicts of interest by the authors.
What is completers analysis?
Completer sample—analyses conducted for only those patients who completed the medication/treatment phase. False inclusion—after randomisation, participants were found to not meet the inclusion criteria and were subsequently removed from the analyses.
What does LOCF mean?
Last Observation Carried Forward
Last Observation Carried Forward (LOCF) is a common statistical approach to the analysis of longitudinal repeated measures data where some follow-up observations may be missing.
What is an on-treatment or per protocol analysis?

What is the meaning of intention to treat analysis?
Intention-to-treat analysis. In medicine an intention-to-treat ( ITT) analysis of the results of an experiment is based on the initial treatment assignment and not on the treatment eventually received. ITT analysis is intended to avoid various misleading artifacts that can arise in intervention research such as non-random attrition
What is ITT analysis in medicine?
In medicine an intention-to-treat (ITT) analysis of the results of an experiment is based on the initial treatment assignment and not on the treatment eventually received. ITT analysis is intended to avoid various misleading artifacts that can arise in intervention research such as non-random attrition of participants from the study or crossover .
