Log-ranked assessment having equivalence regarding setting were did to show if the difference on endurance plots had been mathematically significant. Fundamentally, in the multivariate emergency analysis, Cox proportional issues regression data are utilized to determine risk ratios on the time out-of intimate first of the sex; because of the nature of your own multistage testing build, i generated powerful fundamental mistakes to help you make up you’ll be able to clustering outcomes.
Efficiency
you are percent away from respondents was old fifteen–16, while forty two% have been 17–20 and you can 33% was indeed 21–24; half of was in fact men and half have been lady (Desk step one, page 197).
