WebObjectives: The balance of confounding factors between treatment groups is supported by intention-to-treat (ITT) principle and this can reduce bias and confounding effects. Therefore clear definition of analysis set and blind review are essential prerequisites to perform statistical analysis. Randomized clinical trials analyzed by the intention-to-treat (ITT) approach provide unbiased comparisons among the treatment groups. Intention to treat analyses are done to avoid the effects of crossover and dropout, which may break the random assignment to the treatment groups in a study. ITT analysis provides information about the potential effects of treatment policy rather than on the potential effects of specific treatment.
