⁺Wij is the weighted win loss statistics using weight (i) for the terminal event and weight (j) for the non-terminal event listed in Section 4.1;

^#the percentages in the parentheses are the contribution indexes as, for example, a/(a + b + c + d) × 100%;

^*p-values are from the tests based on the weighted win difference.
