Table 4.
Inter- and intra-group distribution of U1-SN angular measurement.
| U1-SN angle (degrees) | Group 1 (n = 15) Mean ± SD |
Group 2 (n = 15) Mean ± SD |
Inter-group comparison (P-value for unpaired ‘t’ test) |
|---|---|---|---|
| Pre-intrusion | 105.9 ± 6.3 | 104.7 ± 5.4 | 0.582 (NS) |
| Post-intrusion | 105.0 ± 5.7 | 108.5 ± 4.5 | 0.075 (NS) |
| Amount of change | 0.93 ± 1.27 | −3.73 ± 1.28 | 0.001 (S) |
| Intra-group comparison (P-value for paired ‘t’ test) Pre v/s Post |
0.014 (S) | 0.001 (S) |
P-value < 0.05 is considered to be statistically significant. S: Significant, NS: Non-Significant.
