Comparison of disease-free survival between the laparoscopic and open groups. (a) Disease-free survival in all patients, before 1:1 propensity score matching. (b) Disease-free survival in all patients, after 1:1 propensity score matching. (c) Disease-free survival in patients with tumor ≤ 5 cm, after 1:1 propensity score matching. (d) Disease-free survival in patients with tumor > 5 cm, after 1:1 propensity score matching. (e) Disease-free survival in patients with tumor at favorable location, after 1:1 propensity score matching. (f) Disease-free survival in patients with tumor at unfavorable location, after 1:1 propensity score matching. (g) Disease-free survival in patients with very low to intermediate risk by National Institutes of Health classification, after 1:1 propensity score matching. (h) Disease-free survival in patients with high risk by National Institutes of Health classification, after 1:1 propensity score matching.
