SNHG5 and neoplasm: Analysis of the pooled ORs with 95% CIs revealed that elevated SNHG5 expression was associated with increased tumour size (OR: 1.571, 95% CI 1.090–2.264) (Fig. 5); moreover, there were no significant associations between SNHG5 expression and DM (OR: 0.449, 95% CI 0.077–2.630) (Fig. 6A), histological grade (OR: 2.098, 95% CI 0.910–4.838) (Fig. 6B), depth of invasion (OR: 1.106, 95% CI 0.376–3.248) (Fig. 6C), age (OR: 0.946, 95% CI 0.718–1.247) or sex (OR: 0.762, 95% CI 0.521–1.115) (Table 4).
