  1. Data are numbers (%) unless otherwise specified. Percentages may not total 100 because of rounding.
  2. #Two-sided chi-square test; no adjustment for multiple comparisons.
  3. ECOG performance status scores are on a scale of 0–5, with higher scores indicating greater disability.
  4. A value of 1 represents no systemic therapy after platinum resistance; a value of 2 indicates systemic therapy after platinum resistance.
