Kaplan–Meier local tumor progression (LTP) in the CT-guided group versus MR-guided group; a. Mean LTP was 44.264 months (95% CI: 39.484, 49.043) in the CT-guided group versus 47.745 months (95% CI: 43.840, 51.650) in the MR-guided group (P = 0.629, log-rank test). Kaplan–Meier overall survival (OS) of the CT-guided group versus the MR-guided group. b. The mean OS was 56.772 months (95% CI: 53.858, 59.889) in the CT-guided group versus 58.123 months (95% CI: 56.375, 59.889) in the MR-guided group (P = 0.630, log-rank test). The 1-, 3-, and 5-year LTP rates in patients in the CT-guided group were 93.6, 69.5 and 30.7%, respectively, and the 1-, 3- and 5-year OS rates were 100.0, 91.3 and 75.8%, respectively. The 1-, 3-, and 5-year LTP rates in the MR-guided group were 96.3, 81.2% and 28,7%, respectively, and the 1-, 3- and 5-year OS rates were 100.0, 96.2 and 79.4%, respectively
