Demographic Variables and Duration of Surgery among the Three Groups
| Variables | Group C (n = 19) | Group S (n = 18) | Group P (n = 18) | P value |
|---|---|---|---|---|
| Age (yr) | 51.0 ± 11.3 | 48.2 ±10.4 | 45.7 ± 13.2 | 0.382 |
| Weight (kg) | 59.5 ± 12.2 | 59.0 ±14.2 | 60.5 ±7.3 | 0.921 |
| Height (cm) | 159.4 ±8.1 | 156.3 ± 5.5 | 158.2 ± 7.5 | 0.411 |
| BMI (kg/m2) | 23.6±5.5 | 24.4±7.0 | 24.4±4.1 | 0.861 |
| Duration of surgery (min) | 118.6±21.8 | 117.2±31.4 | 119.6±28.2 | 0.962 |
Values are presented as the mean ± SD, a one-way analysis of variance was used to compare the means. A P value of < 0.05 was considered statistically significant. BMI: body mass index.
