HTATIP2 and neoplasm: Because significant heterogeneity was detected, the random effect model was used and the results showed that low expression of TIP30 was associated with poorer pathological differentiation (random effect model: OR = 1.49, 95% CI: 0.87–2.56), vascular tumor thrombus (random effect model: OR = 2.04, 95% CI: 0.57–7.33), and deep tumor invasion (random effect model: OR = 1.62, 95% CI: 0.80–3.29), but not significantly (Table 4 and Figures L-N in S1 File).
