Moreover, Japanese patients had more frequently synchronous mHSPC (95% vs. 75%), high\u2010volume disease (78% vs. 54%), and visceral metastases (16% vs. 8%). ADT plus androgen receptor pathway inhibitors (ARPI) was used more frequently in Japan (76% vs. 71%), as was the combination of ADT\u2009+\u2009ARPI + docetaxel (17% vs. 11%). Conversely, ADT\u2009+\u2009docetaxel was less commonly used in Japan (7% vs. 19%). Median ttCRPC was 39 vs. 23\u2009months, and median OS was 80 vs. 51\u2009months (Japan vs. Germany). After adjustment for relevant clinical covariates, Japanese cohort affiliation remained an independent predictor of prolonged ttCRPC (HR 0.53,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001) and improved OS (HR 0.54,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).
