Table 1.

Number of events/sample size for exact vs Wu's method (administrative censoring adjustment by equation [4]) for different values of Weibull shape parameter β, accrual time a, and follow-up time f.

3.

a = accrual time in months, f = follow-up time in months.

‘Exact’ refers to the exact calculations done using the chi-square distribution.

Note: The calculations given by Lawless [6] were done using an online calculator by SWOG [7] and only show the total sample size and not the number of events.
