Difference of the 2-year LC data predicted using the Martel, Ohri, and Tai models.

The Martel model was taken as a benchmark in all data. FS = fraction scheme. = the maximum dose was 120% of the prescribed dose. = the maximum dose was 110% of the prescribed dose.  Gy = 30 Gy in 1 fraction and other fraction schemes had similar definition. NA = not available; the Tai model for predicting 2-year LC; statistically significant with value < 0.05 compared with the Martel model.
