Table 5.

Comparison of good responders and poor responders, in terms of change in mean MTT (E1s), post each cycle of NACT compared with baseline (pre-NACT)

Time point comparison Change in MTT (E1s) from pre-NACT to third cycle of NACT Comparison of the two groups in terms of difference of MTT (E1s) from pre-NACT to follow-up NACT cycles
Good responder Poor responder
