Figure 4. Variation curve for differential ions.

Figure 4

The blue line represents the relative abundance of ions in NSCLC sputum and the orange line represents the abundance of ions in control sputum; (A) is the curve of DPPC (1.83 ± 3.18 vs. 12.78 ± 1.55; P < 0.05); (B) is the curve of PG (8.92 ± 6.53 vs. 1.42 ± 0.19; P < 0.05); (C) is the curve of PGP (4.35 ± 6.18 vs. 0.81 ± 0.09; P < 0.05); (DPPC were the sum of the m/z734, m/z756 and m/z772 ions, PG was m/z798 ion and PGP was m/z803 ion). Indicates the contols with values that are significantly lower than the average; these may be high-risk cases of lung cancer, and we intend to follow-up these individuals.
