Mice still measured on each day:
  vehicle d0:8 d3:8 d6:8 d9:8 d12:8 d15:8 d18:8 d21:3
  drug    d0:8 d3:8 d6:8 d9:8 d12:8 d15:8 d18:8 d21:8
Day 21, surviving mice only (biased): n = 3 vehicle, 8 drug; geometric means 1820 and 818 mm3; T/C = 0.45, p = 0.0015
Separate test on each day (log volume, Welch):
  d0:0.897 d3:0.060 d6:0.004 d9:0.001 d12:0.002 d15:0.001 d18:0.000 d21:0.001
Growth rate per mouse (slope of log volume per day, all measurements up to culling):
  mean rate: vehicle 0.1538, drug 0.1020 per day; doubling time 4.5 and 6.8 days
  difference (drug - vehicle) -0.0517 per day (95% CI -0.0731 to -0.0303), p = 0.00014; rate ratio 0.66
