Network meta-analysis of blood NO level in lung cancer patients with different pathological types and stages. (a) network plot of lung cancer patients with different pathological types; (b) network plot of lung cancer patients with different stages; (c) pairwise comparisons of blood NO level in controls and lung cancer patients with different pathological types; (d) pairwise comparisons of blood NO level in controls and lung cancer patients with different stages; (e) direct and indirect comparisons between two groups with different pathological types (SCC vs. SCLC, ADC vs. SCLC and LCC vs. SCLC); (f) direct and indirect comparisons between two groups with different stages (early stage vs. advanced stage)
