* The upper and lower confidence limits are the 2.5^th and 97.5^th percentile based on bootstrap replications
xxx = non-existent
(I): PE strategy is inferior compared to RP treatment
(D): PE strategy dominates RP treatment
Note 1: the above presented incremental costs and effects are based on change scores instead of the absolute costs and effects as presented in Table 4.
Note 2: # negative ICERs should be interpreted with caution.
