Neither the patients nor the clinician evaluating their pregnancy knew who had received the true treatment.

A larger sample size and the inclusion of a placebo group is recommended to reveal true treatment outcomes and trends.
The estimated treatment effect for this model may underestimate the true treatment effect by up to 13%.
Much more data that includes a placebo control will be required before a conclusion can be made that acupuncture has a true treatment effect on IVF outcomes.
Without some insight on likely mechanism, trial conditions may not be optimum to allow a true treatment effect to be detected.
The effects of different sample sizes, true treatment effects and choice of priors on the treatment effect and variance estimates were also evaluated.
Additionally, in such specifications the standard errors increase, as the specification leaves little time variation for identification of the true treatment effect.
We considered that a true treatment effect altering tumor glucose uptake was one based on a physiological change in the tumor tissue per se.
Two-sample two-sided t-test p-values were calculated in these three true treatment studies: A, B, and C described in Table 1.
It is nonsensical to argue about what is "true" treatment and which recovery is "true" recovery.
