  REGROWTH          
  1. n: number of tumours.
  2. R: correlation coefficient. Median time interval is calculated from measurement time intervals between the first and the second tumour volume measurements. NA: not available. NS: not statistically significant (p-values in parentheses). DTe: equivalent doubling time. DTe and uncertainty calculations were done according to previously published methods[7]. Regrowth in the last row means that the calculation has been done for regrowth of tumours after induction chemotherapy.
