Correlation between the specific growth rate, SGR, and the logarithm of tumour volume in groups of patients diagnosed with the same type of tumour
| Tumour type | Reference | n | R2 | p (1-tailed) | Median time interval (days) | Median time interval/DTe | Average SGR (%/d) | Relative uncertainty of SGR (%) | DTe (days) | Relative uncertainty of volume estimation (%) |

| REGROWTH |
n: number of tumours.
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.
