In this analysis, 148 and 84 patients in the R and O groups, respectively, were matched based on baseline characteristics, resulting in 82 patients in each group. Survival curves were drawn from inclusion. Of the 149 LyMa-ITT patients, 1 patient withdrew his consent, leading to 148 patients analyzed. Of the 86 patients included in LyMa-101, 1 withdrew his consent and 1 had missing data for matching.
Fisher test was performed between matched populations.
A total of 120 randomized and 28 nonrandomized patients.
