Patients' general characteristics.
| Patients' general characteristics | Pre-invasive GGNs | Invasive GGNs | p |
|---|---|---|---|
| Gender (female/male) | 74 (69.2%)/33 (30.8%) | 215 (60.2%)/142 (39.8%) | 0.058 |
| Age | 54.8 ± 10.8 | 58.1 ± 13.4 | 0.021 |
| Lesion volume (mm3) | 174.1 ± 253.9 | 841.2 ± 1380.8 | <0.001 |
| Intensity | −342.4 ± 135.6 | −355.1 ± 127.0 | 0.372 |
| Location (right/left) | 69 (64.5%)/38 (35.5%) | 209 (58.5%)/148 (41.5%) | 0.162 |
| Follow-up patients (group A/B/C) | 48 (30/8/10) | 331 (173/79/79) | / |
| Mean follow-up interval (months) | 8.5 | 8.0 | / |
The gender and location characteristics were compared by Chi-square test, while age, lesion volume, and intensity characteristics were compared by ANOVA. p < 0.05 has statistical significance.
