Across five studies with a total of 1403 subjects, high CCR7 levels were not significantly associated with tumor size (OR 1.062, 95% CI 0.630 to 1.791; Egger’s test p value 0.621; LFK index 2.59 [major asymmetry]; Figure 3B) (see the funnel and Doi plots in Figures S3 and S4). The gene discussed is CCR7; the disease is neoplasm.
