Significantly changed metabolites in serum of lung cancer and other lung diseases

Metabolites	P*	Tendency	Ratio (lung cancer/other lung diseases)
*Statistical P-value calculated using a two sample t-test (significance at P < 0.05); ↑: The level of the metabolites is higher in lung cancer than in other lung diseases; ↓: The level of the metabolites is lower in lung cancer than in other lung diseases.
