Table 3.

The power that can be achieved by the rapid atrial fibrillation and flutter 3 (RAFF-3) trial to detect a standardised effect size of 0.4 with two-sided significance level of 0.05.

$ρ_{d}$	$r_{d}$	Power
0.050	1.000	0.962
0.061	0.949	0.905
0.102	0.800	0.714
0.200	0.552	0.547

The values of $ρ_{d}$ and $r_{d}$ are consistent with ${\hat{ρ}}_{e} = 0.05$ by applying the exchangeable model to the length of stay outcomes in the RAFF-3 trial.
