The most commonly used time intervals including goal and actual values.

(a) The different combination schemes of timing to surgery and BED₁₀ with OTT correction, including distribution of goal time intervals. The upper color in the right means higher frequency of use in clinical practices; and (b) the correlation between goal and actual intervals, including distribution of time to surgery of the National Cancer Database. In most trials, the median values of actual time intervals were presented, but the mean values were seldom reported. Moreover, a linear function was fitted to the mean values of both goal and true time intervals, and the fitting parameter was 1.01 ± 0.09. If the goal interval was represented by a range using the sign of ‘> or ⩾’, the minimum value was used in this figure, and the sign of ‘→’ was attached. Otherwise, we used the mean values of goal interval.

BED, biologically effective dose; OTT, overall treatment time; p0, the fitting parameter; Prob, probobility; ndf, the number of degrees of freedom.
