P1: value of LN detection rate; P2: value of SLN double-sided detection rate; g, i value between the total detection rates of each group; h value between the total detection rate of stage I and stage II, j value of bilateral detection rate between groups, and k value of double-sided detection rate between ≦ 2/3 and >2/3; denotes statistically significant difference.
