Fig. 3: Quantification of treatment regime outcomes.

a Cumulative days of drug delivery (measured as the sum of drug delivery days over 590 days of therapy) against relative tumour burden (measured as the sum of total cancer cell count over the t ∈ [0, 590] day window normalised to the continuous treatment case) for \({\tau }_{T}=\left\{10,20,30,40,50,60,70,80,90,100\right\}\) days and τH = 20 days. For each schedule, averages over 30 simulations and 95% confidence intervals are shown. The star indicates reference measures for continuous treatment. As τT is increased, relative tumour burden initially decreases and cumulative days of drug delivery increases, but from τT = 50 days, the relative tumour burden increases. b The inset zooms in on measures for schedules with τT ≥ 40 days. The treatment regime τT = 50 days, τH = 20 days is chosen for further analysis.
