Table 2 Local tumor control of tumor models. a) Tumor control rate (TCR) until day 120–180 after RCTx with 30 fractions in 6 weeks, weekly cisplatin and nimorazole or carrier. b) Hazard ratios (HR) and corresponding 95% confidence intervals of RCTx + nimorazole vs RCTx + carrier and RCTx + nimorazole (after 10fx) vs RCTx + carrier, p values after (p adj) correcting for multiple testing

From: Prognostic biomarkers for the response to the radiosensitizer nimorazole combined with RCTx: a pre-clinical trial in HNSCC xenografts
