SIGLEC1 and hepatocellular carcinoma: A fixed model was used because of no significant heterogeneity (P = 0.674, I2 = 0), and the result demonstrated that high density of intratumoral CD169+ TAMs in patients with HCC was associated with a good OS (pooled HR = 0.471; 95% CI = 0.343–0.647; P = 0.037).
