SF2, sensitiser / control, one ratio per experiment (paired, n = 5): 1.06 (95% CI 0.96 to 1.17), p = 0.17
Dose enhancement ratio at SF = 0.1, one per experiment (paired, n = 5): 0.96 (95% CI 0.88 to 1.05), p = 0.26
All 120 dishes pooled, Poisson model (plating efficiency per experiment and condition): likelihood-ratio chi2(2) = 10.3, p = 0.0059; Pearson dispersion 2.3
Same model with quasi-Poisson scaling: F(2, 106) = 2.18, p = 0.12
