“…According to the detection area of lymphatic vessels, the studies were also divided into three subgroups of total LVD ( n = 15) [11, 12, 14, 15, 17, 19, 20, 24, 25, 27–31, 37], peritumoral LVD ( n = 8) [16, 18, 22, 27, 34–36, 38], and intratumoral LVD ( n = 5) [18, 22, 27, 34, 38]. The pooled Fisher's Z values were show in Figure 3, corresponding to the r values of total LVD ( r = 0.32, 95% CI: 0.19 to 0.45), peritumoral LVD ( r = 0.33, 95% CI: 0.18 to 0.46), intratumoral LVD ( r = 0.29, 95% CI: 0.04 to 0.50), and overall LVD ( r = 0.32, 95% CI: 0.23 to 0.40), respectively (Figure 3, Table 4).…”
