E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome for dabigatran is a major vascular complication (i.e., a composite of vascular mortality, nonfatal myocardial infarction, nonfatal stroke, nonfatal peripheral arterial thrombosis, and nonfatal symptomatic pulmonary embolism). The primary outcome for omeprazole is a major upper gastrointestinal complication (i.e., a composite of overt gastroduodenal bleeding, overt upper gastrointestinal bleeding of unknown origin, or upper gastrointestinal perforation). |
La variable principal de dabigatrán es una complicación vascular mayor (es decir, una combinación de la mortalidad vascular, infarto de miocardio no fatal, accidente cerebrovascular no fatal, trombosis arterial periférica no fatal y no fatal embolia pulmonar sintomática). La variable principal para el omeprazol es una complicación a nivel gastrointestinal superior (es decir, una combinación de hemorragia gastroduodenal manifiesta, sangrado gastrointestinal superior abierta de origen desconocido, o perforación gastrointestinal superior). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
3 interim efficacy analyses based on the primary outcome will occur when 25% 50% and 75% of the patients have been followed average for 1 year. Data Monitoring Committee (DMC) will employ the modified Haybittle-Peto rule of 4 standard deviations (SDs) (a=0.0001) for analyses in the first half of the trial (including the second planned interim analysis) and 3 SDs (a=0.00047) for all analyses in the second half. For a finding of 1 or both active treatments to be considered significant, these predefined boundaries will have to be exceeded in at least 2 consecutive analyses, 3 or more months apart. A-level for the final analysis will remain the conventional a=0.05 given the infrequent interim analyses, their extremely low a levels, and the requirement for confirmation with subsequent analyses. |
Tres análisis intermedios/provisionales de la eficacia basados en la variable principal, se realizaran cuando el 25%, el 50% y el 75% de los pacientes hayan sido seguidos en promedio durante 1 año, además del análisis final que se realiza al final del ensayo. |
