Regarding the above mentioned differences between the two radiation dose groups ( Table 2 ), MVA revealed that the only significant factor that impacts LC is histology (N = 188; HR 2.234 95%-CI 1.399–3.566; p -value < 0.001; Table 3 ) with total radiation dose (>/<66 Gy) showing borderline significance ( p -value = 0.059).
