| Position, Rater |
Mean ± SD |
Standard Error of Measurement |
| Side lying, rater 1 | 105.9 ± 11.8a | 1.9 |
| Side lying, rater 2 | 100.8 ± 14.2a | 2.3 |
| Supine with overpressure, rater 1 | 110.8 ± 11.6b | 1.9 |
| Supine with overpressure, rater 2 | 114.3 ± 18.5b | 3.0 |
| Supine without overpressure, rater 1 | 90.3 ± 15.5c | 2.5 |
| Supine without overpressure, rater 2 | 88.3 ± 16.4c | 2.7 |
a
Indicates difference between side-lying and supine-with-overpressure positions, based on Bonferroni adjusted P values.
b
Indicates difference between supine-with-overpressure and supine-without-overpressure positions, based on Bonferroni adjusted P values.
c
Indicates difference between side-lying and supine-without-overpressure positions, based on Bonferroni adjusted P values.
