Attempts by untrained operators (N = 32) | Average ± SD | Min | Max | Median | 25th percentile | 75th percentile | p value |
|---|---|---|---|---|---|---|---|
Attempts with the standard method (N) | 1.87 ± 1.53 | 1 | 7 | 1 | 1 | 2 | p < 0.050 |
Attempts with the tTNI (N) | 1.28 ± 0.5 | 1 | 3 | 1 | 1 | 1 | |
Time required for standard method (s) | 46.8 ± 65.73 | 6 | 300 | 22.5 | 17 | 36.25 | p < 0.001 |
