Scenario 2 power plot, where the end of study time is fixed at 40 days, but with random censoring during the study period. Power is estimated at a 5% significance threshold. Lines with circular points characterise the Cox proportional hazards model and lines with square points the logistic regression model. The colour of the line corresponds to the rate of censoring defined by the scale parameter of the Weibull distribution: scale 20 (black); scale 40 (red); scale 60 (green).
