Statistical Analysis 1 for Overall Survival (OS)
Groups [1] Interferon Alfa vs. Temsirolimus
Non-Inferiority/Equivalence Test [2] Yes
Method [3] Log Rank
P Value [4] 0.0252
Cox Proportional Hazard [5] 0.78
95% Confidence Interval ( 0.63 to 0.97 )
[1] Additional details about the analysis, such as null hypothesis and power calculation:
  No text entered.
[2] Details of power calculation, definition of non-inferiority margin, and other key parameters:
  2 null hypotheses (Ho) were tested: 1) Survival distributions for temsirolimus alone and Interferon Alfa (IFN)-alone treatment groups were identical. 2) Survival distributions for temsirolimus in combination with IFN and IFN-alone treatment groups were identical. The alternative hypothesis (Ha) for each test was that the survival distributions differed.
[3] Other relevant method information, such as adjustments or degrees of freedom:
  Stratified by prior nephrectomy and region
[4] Additional information, such as whether or not the p-value is adjusted for multiple comparisons and the a priori threshold for statistical significance:

Certain Agreements:  
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
The agreement is:
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.


Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Efficacy data was not collected or analyzed after the primary analysis was completed.
