The phrase "axis trial" is not a standard expression in written English and may not be widely recognized.
It could potentially be used in a specific context related to scientific research or clinical studies, but clarity would depend on the surrounding text.
Example: "The results of the axis trial provided new insights into the effectiveness of the treatment."
Alternatives: "axis study" or "axis experiment".
Data from both arms of the trial were merged: this was justified because neither treatment had an impact on the excess hazard of death, which corroborates the main result of the AXIS trial (The AXIS collaborators, 2003).
The AXIS trial confirmed the overall safety profile of axitinib.
More important, there was no evidence of a deprivation gap in survival in the AXIS trial.
In the AXIS trial, however, the socioeconomic distribution of patients was unknown at randomisation.
Furthermore, all analyses were pre-specified secondary end points of the AXIS trial.
Median PFS, OS, and SPP as observed in the AXIS trial is shown in Table 1.
Therefore, one might find no deviation from chance in horizontal axis trials despite high within-trial persistence if there were arbitrary initial choices across trials (N.B. vertical axis trials were always separated by horizontal axis trials).
Prior to the beginning of a trial, the observer was cued to use either the Left and Right arrow keys (vertical axis trials) or the Up and Down arrow keys (horizontal axis trials).
Therefore it is not the case that there is a within-trial perceptual persistence masked by inter-trial randomness of initial percept in the horizontal axis trials.
In the vertical axis trials observers reported the target cube as viewed-from-above more than 90% of the time in both array and single cube trials.
The much weaker modulation in the vertical axis trials may be a ceiling effect, reflecting the dominance of the viewed-from-above prior in this case.
