En af de to undersøgelser viste en statistisk signifikant forsinkelse i tid til progression af invaliditet (risikoforhold = 0, 69, 95% konfidensinterval (0, 55, 0, 86), p = 0, 0010, svarende til en 31% risikoreduktion forårsaget af Betaferon) og i tid til kørestolsafhængighed (risikoforhold = 0, 61, 95%
One of the two studies demonstrated a statistically significant delay in the time to disability progression (Hazard Ratio = 0.69, 95% confidence interval (0.55, 0.86), p=0.0010, corresponding to a 31% risk reduction due to Betaferon) and in the time to becoming wheelchair bound (Hazard Ratio = 0.61, 95% confidence interval (0.44, 0.85), p=0.0036, corresponding to a 39% risk reduction due to Betaferon) in patients who received Betaferon.
