Comparison of DNA ploidy parameters between SCLC and NSCLC groups
| SCLC | NSCLC | U/χ2 | P | |
|---|---|---|---|---|
| Max DI, M (P25, P75) | 5.26 (3.83, 6.86) | 5.92 (4.17, 7.39) | 2507.00 | 0.122 |
| Median DI, M (P25, P75) | 3.38 (2.43, 3.98) | 3.62 (2.74, 4.18) | 2722.00 | 0.444 |
| 5cER, M (P25, P75) | 0.1217 (0.0254, 0.2093) | 0.1506 (0.0642, 0.3343) | 2392.00 | 0.05* |
| Distribution of aneuploid peaks, DI value (%) | - | - | 11.64 | 0.008* |
| No aneuploid peak | (6%) | (24.4%) | - | |
| Single aneuploid peak | 1.2-1.8 (47.7%) | 1.2-1.8 (32.9%) | ||
| Double aneuploid peak | 2.5-3.5 (40.3%) | 2.5-4.2 (31.9%) | ||
| Multiple aneuploid peak | 2.5-3.2 (6%) | 3.0-5.0 (10.8%) | ||
Notes: Max DI represents for the maximum DI; median DI, namely, the median DI of the first 20 cells greater than 5C; 5cER: 5c exceeding rate. We used 5cER to represent the percentage of cells with DI greater than 5c in this study. The DI value of a single aneuploid peak refers to the DI value of the first aneuploid peak, the DI value of double aneuploid peaks refers to the DI vale of the second one, and the DI value of multiple aneuploid peaks refers to the DI value of the third one.
