Comparison of CWT between the second ICS-MCL and fifth ICS-MAL on different planes.
| Radial depth | DVSclose | |||
|---|---|---|---|---|
| Left | Right | Left | Right | |
| Second ICS-MCL | 3.22 (1.03) | 3.18 (1.02) | 8.99 (1.53) | 8.85 (1.24) |
| Fifth ICS-MAL | 3.65 (1.51) | 3.91 (1.72) | 9.83 (1.96) | 10.40 (2.16) |
| 95% CI | (−0.61, −0.25) | (−0.94, −0.53) | (−1.01, −0.61) | (−1.91, −1.20) |
| P | 0.001 | 0.001 | 0.001 | 0.001 |
Data are expressed as mean ± standard deviation. P values of the paired-samples t-test are shown in the table. CWT, chest wall thickness; second ICS-MCL, second intercostal space at the midclavicular line; fifth ICS-MAL, fifth intercostal space at the midaxillary line.
