  • NOTE: For the Karnofsky score, a division in three categories (≤60, 70 and 80, 90, and 100) is considered. As such, two HR estimates are reported. The first indicating the change in hazard when comparing patients with a Karnofsky index of 70 or 80 and patients with a Karnofsky index higher than 80. The second indicating the change in hazard comparing patients with a Karnofsky index lower than or equal to 60 and patients with a Karnofsky index of than 70 or 80. P values in bold refer to the effect of a predictor with more than 1 degree of freedom.

    Abbreviations: LL/UL, lower and upper limit of the 95% CI for the HR.
